weak acid and strong base examples

Strong acid add all their H+ to will weak acid only add some H+ to solution. Let’s check more examples of acids and bases in everyday life. What is salt of weak acid and strong base. pH value is used to express strength of acids and bases. Weak acids have relatively low pH values and are used to neutralize strong bases. Sulfuric (H 2 SO 4(aq)) is a strong acid. Weak acid: AH + H 2 O ↔ A-(aq) + H 3 O + (aq) The strongest weak acid is the hydronium ion (H 3 OR + ), which is considered the border between weak acids and strong acids. Key Points. Quora. Strong acid is an acid that ionize completely while weak acid partially ionize. https://www.thoughtco.com/list-of-strong-and-weak-acids-603642 (accessed January 24, 2021). While acids tend to be corrosive, the strongest superacids (carboranes) are actually not corrosive and could be held in your hand. When the acid dissociation constants are close to 1 or much larger than 1, there acids are strong as the molecules fully dissociate into ions. In other words, the acid is concentrated. Here are two slides from the beginning of my acid/base lecture series. Strong Acids and the World's Strongest Acid. The strength of a weak organic acid may depend on substituent effects. So a base based on some other mechanism, such as NH3 (which does not contain OH− ions as part of its formula), will be a weak base. However, the reaction is reversible, and at any one time about 99% of the ammonia is still present as ammonia molecules. The primary difference between strong and weak acids is how the behave in water. There are only a few (7) strong acids, so many people choose to memorize them. Because this reaction does not go 100% to completion, it is more appropriate to write it as a reversible reaction: \[HC_{2}H_{3}O_{2}\rightleftharpoons H^{+}(aq)+C_{2}H_{3}O_{2}^{-}(aq)\]. The nitrogen in C 5 H 5 N would act as a proton acceptor and therefore can be considered a base, but because it does not contain an OH compound, it cannot be considered a strong base; it is a weak base. Some of such salts are : CH 3 COONa, Na 2 CO 3, K 2 CO 3, KCN etc .For our discussion, we consider CH 3 COONa (sodium acetate) in water. With pOH obtained from the pOH formula given above, the pH of the base can then be calculated from = −, where pK w = 14.00. Na2CO3 is a Bronsted- Lowry base without hydroxide groups, but has the ability to accept hydrogens. Helmenstine, Anne Marie, Ph.D. (2020, August 27). Stronger acids are close to 1, and weak acids are close to 7. Define a strong and a weak acid and base. If we ignore the above discussed definitions we can easily identify an acid … Is HF (Hydrofluoric Acid) a Strong Acid or a Weak Acid? 1) The reaction of interest is this one: CH 3 NH 2 + H 2 O ⇌ CH 3 NH 3 … It is important that you don't confuse the words strong and weak with the terms concentrated and dilute.. As you will see below, the strength of an acid is related to the proportion of it which has reacted with water to produce ions. So Ba(OH) 2(aq) react with HCl and give barium sulphate ( BaSO4(s) ) and water as products. Any other acid is considered a weak acid. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Weak bases, such as baking soda or egg white, should be used to neutralize any acid spills. Furthermore, weak acids and bases are very common, and we encounter them often both in the academic problems and in everyday life. An aqueous solution of sodium hydroxide, NaOH (aq) , is an example of a strong base. The difference between a Strong base and a Weak base is that a strong base ionized completely or 100% in an acid-base reaction or water or solution whereas a weak base is incapable of completely ionizing in a reaction or a solution, it may ionize 1% or 99%. (2016). If it does not dissociate 100%, it is a weak acid. There are many more weak acids than strong acids. “Strong Base: Definition & Examples.” Study.com, Available here. The main difference between a strong base and a weak base is that strong bases can completely dissociate to give all available hydroxyl ions to the system whereas weak bases are partially dissociated to give some of their hydroxyl ions. There are seven strong acid She has taught science courses at the high school, college, and graduate levels. No strong acid has been added, so this solution is simply a solution of a weak base. Everything else is considered weak. Q: Alkalis are which of the following 1. weak acids 2. strong acids 3. weak base 4. strong baseSol: The correct answer is option ‘d’. Inorganic Chemistry. While technically a weak acid, hydrofluoric acid is. This page explains the terms strong and weak as applied to acids. As it turns out, there are very few strong acids, which are given in Table \(\PageIndex{1}\). This is one of the strong acids secreted by the walls of our stomach in the gastric juice. Imagine an experiment in which a 10.00 mL aliquot of 0.200 mol L -1 CH 3 COOH (aq) is transferred to a clean conical flask (erlenmeyer flask). Hydrofluoric acid, while a weak acid, would pass through your hand and attack your bones. A strong acid is one that dissolves in water. References: 1. pH titration curves for weak acids and weak soluble bases (alkalis) - relating to feasibility of a quantitative titration. Some common weak acids and bases are given here. HCl; Mg(OH) 2; C 5 H 5 N; Solution. They have pH between 10 and 14.Strong bases are NH3 ammonia; CH3NH2 methylamine; C5H5N pyridine *Remember any base that dissolves in water is an alkali and must have a pH above 7! Weak acids incompletely ionize. Yes, pure water acts as a weak base. All the other acids are weak. This is because a small amount of water dissociates into protons and hydroxide anions, binding with the remaining water molecules to form hydronium ions and hydroxide ions. Here is a partial list, ordered from strongest to weakest. Such salts give alkaline solutions in water. In fact, it has its own abbreviation of HAc, where H means hydrogen and Ac means acetate. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. At equilibrium, both the acid and the conjugate base are present in solution. The acid-base reaction will produce salt and water. Superbases . Examples: CH 3 COOH and H 2 CO 3; The dissociation of a weak acid is a reversible reaction that reaches equilibrium; Only small portion of acid molecules have dissociated at equilibrium; Conjugate base of weak acid is strong base Calculate the pH of the solution after these volumes of the titrant have been added. https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FCollege_of_Marin%2FCHEM_114%253A_Introductory_Chemistry%2F14%253A_Acids_and_Bases%2F14.07%253A_Strong_and_Weak_Acids_and_Bases, 14.6: Acid–Base Titration- A Way to Quantify the Amount of Acid or Base in a Solution, information contact us at info@libretexts.org, status page at https://status.libretexts.org. Titration of a weak base with a strong acid (video) | khan academy. Weak acids and bases are less than 100% ionized in aqueous solution. The negative logarithm of the hydroxide ion concentration is called pOH. Helmenstine, Anne Marie, Ph.D. "List of Strong and Weak Acids." Strong and Weak Acids. The neutralization of nitric acid with ammonia results in the ammonium nitrate compound, as shown below: When reaction occurs, you can see this white precipitate forms bottom of the plask. The conjugate base of a moderately weak acid is a moderately weak base. The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid. Because Ca(OH)2 is listed in Table \(\PageIndex{1}\), this reaction proceeds 100% to products. Accessed 14 Sept. 2017. A simple example is base solution found in the gastritis drug. For More Chemistry Formulas just check out … Chemteam: weak acids/bases titrated with strong acids/bases. Below are two graphs showing the titration of the neutralization reaction of a strong acid with a strong base and a strong base with a strong acid, where its equivalence point is also represented: Strong acid + weak base . Strong acids have high Ka or small pKa values, weak acids have very small Ka values or large pKa values. The ChemTeam will try to use several different weak acids in the examples to follow. CH3COOH (acetic acid) HCOOH (formic acid) HF (hydrofluoric acid) HCN (hydrocyanic acid) HNO2 (nitrous acid) HSO4- … What are some examples of strong acids and weak bases? Superbases are Lewis bases that are Group 1 salts of carbanions, such as hydrides and amides. The time honored example weak acid is acetic acid. Because HCl is listed in Table \(\PageIndex{1}\), it is a strong acid. Strong acids are not named as such because they are more powerful than other acids. Because HCl is listed in Table \(\PageIndex{1}\), it is a strong acid. Calculating ph for titration of weak base with strong acid chemistry. Weaker acids and bases have equilibrium positions farther to the left. The most common example among weak bases is ammonia (NH 3). pH and pOH. When HCl is dissolved in H2O, it completely dissociates into H+(aq) and Cl−(aq) ions; all the HCl molecules become ions: \[HCl\overset{100\%}{\rightarrow}H^{+}(aq)+Cl^{-}(aq)\]. HA ⇌ H+ + A−. Consider HCl(aq). There are really only a few stong acids and bases. Monobasic acids: HCl, Nitric acid, acetic acid Dibasic acids: Sulphuric acid, phosphorous acid Tribasic acids: phosphoric acid b) The base is a substance that ionize in water to give OH–ions. Strong acid passes electricity faster whereas weak acids are slow conductors. Alkalis are water-soluble bases. Sulfuric acid. Strong acids are not named as such because they are more powerful than other acids. In fact, it has its own abbreviation of HAc, where H means hydrogen and Ac means acetate. Weak Base: The solution of a weak base has a lower electrical conductivity than this of a strong base. An acid or base is classified as strong if it is fully ionized in solution (e.g. Strong Base: The solution of a strong base has a higher electrical conductivity than this of a weak base. This is an ionic compound of Ca2+ ions and OH− ions. In section 7. pH titration curves were introduced by looking what happens when you add a strong acid to a strong alkali. Weak base wikipedia. it is still said to be a weak base. For example, NH3 is a Lewis base, because it can donate the electron pair on nitrogen. Strong and Weak Acids and Bases! A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other. If it is less than 100% ionized in solution, it is a weak base. As a part of this it defines and explains what is meant by pH, K a and pK a.. plz anyone help me out. Weak bases. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The ChemTeam will try to use several different weak acids in the examples to follow. Thus, in water, strong acids or bases will ionize more than weak acids or bases. In fact, pure water acts as both a weak acid and a weak base. The time honored example weak acid is acetic acid. If an acid is not listed here, it is a weak acid. A dilute acid is an acidic solution that contains a lot of solvent. The strength of a weak acid is quantified by its acid dissociation constant, pKa value. Any acid that dissociates 100% into ions is called a strong acid. When CH 3 COONa is put in water, it completely ionises to give CH 3 COO-(acetate) ions and Na + ions. Strong acids and bases are 100% ionized in aqueous solution. Common examples of strong bases are the hydroxides of alkali metals and alkaline earth metals, such as NaOH and Ca(OH)2. The most common example among weak bases is ammonia (NH 3). The number of protons given off by a particular acid actually determines the strength of the acid – whether it is a strong acid or a weak acid. You can drink diluted acetic acid (the acid found in vinegar), yet drinking the same concentration of sulfuric acid would give you a chemical burn. Salts formed from neutralization reaction between weak bases and strong acids are found to be acidic in nature. A weak Brønsted-Lowry acid has very little tendency to donate a proton. Acid-base pairs, strength of acids and bases, and ph. Write the balanced chemical equation for the dissociation of Ca(OH)2 and indicate whether it proceeds 100% to products or not. An example of a strong acid – weak base titration is the reaction between ammonia (a weak base) and hydrochloric acid (a strong acid) in the aqueous phase: NH3(aq)+HCl(aq) → NH+ 4(aq)+Cl−(aq) NH 3 (aq) + HCl (aq) → NH 4 + (aq) + Cl − (aq) The acid is typically titrated into the base. Hence they are strong bases. Stronger acids and bases have ionization equilibrium positions farther to the right. 1-3 is a Strong Acid, 4-7 is a Weak Acid, 7 is Neutral, 8-10 is a Weak Alkali, 11-14 is a Strong Alkali Examples of acids in everyday life: Examples of bases and alkalis in everyday life: Helmenstine, Anne Marie, Ph.D. "List of Strong and Weak Acids." Example \(\PageIndex{1}\): Identifying Strong and Weak Acids and Bases. In order to understand the strength of the acids, one need to compare their tendency to donate protons to the similar base (mostly water). The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. While technically a weak acid, hydrofluoric acid is extremely powerful and highly corrosive. List of Strong and Weak Acids. In an acid-base titration, the titration curve reflects the strengths of the corresponding acid and base. The stronger the acid, the better it dissociates in an aqueous solution, releasing more cationic hydrogen (H +) ions.Examples of strong acids include hydrochloric acid (HCl), hydrobromic acid (HBr), perchloric acid (HClO 4), and sulfuric acid (H 2 SO 4).However, because pH measures the … Acetic acid is an example of a weak acid. No matter how much water you remove, that will be true. Weak acids do not have this ability. Legal. Strong acids are not edible but weak acids are edible. When using a weak acid and a strong base, the steepest part of the titration curve occurs at a pH slightly above 7, so phenolphthalein is also suitable for this type. Calculate the pH of the solution after these volumes of the titrant have been added. Strong acids completely dissociate into their ions in water, while weak acids only partially dissociate. In aqueous solution, each of these essentially ionizes 100%. If you were to add a weak base, like an aqueous solution of ammonia (NH 3(aq)) or ammonium hydroxide (NH 4 OH (aq)), to a strong acid, like sulfuric acid (H 2 SO 4(aq)), then the shape of the conductance curve will be quite different to the shape of the curve for a strong-acid - strong base conductometric titration. Sulfuric acid is categorized as a strong acid that has a very corrosive trait. Weak acids do not have this ability. Salts of a Weak Base and a Strong Acid. Examples of Acids and Bases in Everyday Life; Total Views: 667. Strong bases fully dissociate to give ions in solution. Weak. Examples of strong acids are hydrochloric acid, perchloric acid, nitric acid and sulfuric acid. Learn vocabulary, terms, and more with flashcards, games, and other study tools. titration solution Weak Acid and Strong Base Titration Curve A weak acid only partially dissociates from its salt The pH will rise normally at first, but as it reaches a zone where the solution seems to be buffered, the slope levels out. This video describes how to draw the conductometric titration curve for a weak acid with a strong base (acetic acid/CH3COOH vs sodium hydroxide/NaOH). An example reaction is the dissociation of ethanoic acid in water to produce hydroxonium cations and ethanoate anions: Note the reaction arrow in the chemical equation points both directions. BaSO 4 is a white precipitate. When a weak base and a strong acid are used, the most rapid pH changes and the steepest part of a titration curve occur at a pH less than 7. One drop of sulfuric acid is able to leave a hollow mark in our skin. Strong acids dissociate completely into their ions in water, yielding one or more protons (hydrogen cations) per molecule. Acids and bases are used to manufacture different compounds (NaOH is used to prepare soap), but Acids and bases are toxic and harmful to people and environmental. Weak Brønsted-Lowry acids include H 2 O 2, CH 3 OH and H 2 O. A classification based on acidity constants or pK a values seems natural.. Let’s denote the total amount of the acid by C T ≡ [HA] T (which is de facto the acid’s initial concentration before it dissolves). The term strong in the name refers to the acid’s ability to release hydrogen (H+) molecules, which allows it to become ionized when placed into a solution of water. HC2H3O2 is an example of a weak acid: \[HC_{2}H_{3}O_{2}\overset{\sim 5\%}{\longrightarrow}H^{+}(aq)+C_{2}H_{3}O_{2}^{-}(aq)\]. Strong acids dissociate (break apart) completely in water). For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Strong Base vs Weak Base. Acids and bases are categorized into two kinds as strong and weak. The reaction proceeds in both directions. Such salts give alkaline solutions in water. Key Points. In an acid-base titration, the titration curve reflects the strengths of the corresponding acid and base. Strong and Weak Bases. If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular, and the pH shifts less with small additions of titrant near the equivalence point. There are seven strong acid Porterfield, William W. (1984). Recall that in our lesson on conjugate acids and bases, we learned that in a conjugate pair, the stronger the acid, the weaker the base. The term strong in the name refers to the acid’s ability to release hydrogen (H+) molecules, which allows it to become ionized when placed into a solution of water. Recognize an acid or a base as strong or weak. Addison-Wesley. Concentrated and Dilute. List of Strong Acids. Because Mg(OH) 2 is listed in Table \(\PageIndex{1}\), it is a strong base. Weak acids and bases are only partially ionized in their solutions, whereas strong acids and bases are completely ionized when dissolved in water. Weak bases are only partially ionized in their solutions, whereas strong bases are completely ionized when dissolved in water. Watch the recordings here on Youtube! Acids have pH values from 1 to 7. If it is less than 100% ionized in solution, it is a weak base. The fluid in the stomach causes gastritis contains hydrochloric acid which in normal conditions helps destroy food during the digestive process, that the base gastritis drug can neutralize the gastric acid. A weak base persists in chemical equilibrium in much the same way as a weak acid does, with a base dissociation constant (K b) indicating the strength of the base. Retrieved from https://www.thoughtco.com/list-of-strong-and-weak-acids-603642. This page was constructed from content via the following contributor(s) and edited (topically or extensively) by the LibreTexts development team to meet platform style, presentation, and quality: Marisa Alviar-Agnew (Sacramento City College). ThoughtCo. Determine if a salt produces an acidic or a basic solution. Conjugate base of strong acid is weak base; Weak acid only partially dissociates in water; it is a poor proton donor. This is called the buffer region.This happens because the weak acid will only partially dissociate After this zone the pH will rise sharply … Strong acids dissociate completely in water, while weak acids do not dissociate completely. The only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF). 2. Strong acids dissociate completely in water, while weak acids do not dissociate completely. Salts of weak acids or bases can affect the acidity or basicity of their aqueous solutions. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. 3 Strong Acids. Strong and weak acids are important to know both for chemistry class and for use in the lab. They completely dissociate into hydroxide ions in aqueous medium. Strong acids and strong bases react completely to produce salt and water. You can use the acid equilibrium constant Ka or pKa to determine whether an acid is strong or weak. For example, HF dissociates into the H+ and F- ions in water, but some HF remains in solution, so it is not a strong acid. Strong. Examples of acids in everyday life: Examples of bases and alkalis in everyday life: Vinegar is diluted acetic acid, which is what gives salad dressings and pickled vegetables their tart taste. Examples of strong base are N … Weak Acid Strong Base Titration The titration of 50.0mL of 0.100M HC 2 H 3 O 2 (Ka=1.8 x 10 -5 ) with 0.100M NaOH is carried out in a chemistry laboratory. For example, methanol is a weak Brønsted-Lowry acid: Generally, a strong acid has a pH of about zero to 3. ThoughtCo, Aug. 27, 2020, thoughtco.com/list-of-strong-and-weak-acids-603642. All strong bases are OH – compounds. Ammonium chloride is an example of acidic salt. NaOH dissociates in water to give the hydroxide (OH–) Based on the number of availabl… Neutralizing acid spills with strong bases, such as sodium hydroxide or potassium hydroxide, can cause a violent exothermic reaction, and the base itself can cause just as much damage as the original acid spill. A classification based on acidity constants or pK a values seems natural.. Let’s denote the total amount of the acid by C T ≡ [HA] T (which is de facto the acid’s initial concentration before it dissolves). the weak acid once it has fully reacted with the base will produce a conjugate weak base which will give the solution a basic pH at the equivalence point. Strong acids have ph value ranging between 0 to 3 but the ph value of weak acids ranges between 5 to below 7. The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid. Example \(\PageIndex{2}\): Characterizing Base Ionization. HCl (hydrochloric acid) HNO3 (nitric acid) H2SO4 (sulfuric acid) HBr (hydrobromic acid) HI hydroiodic acid; HClO4 (perchloric acid) Weak. Barium hydroxide (Ba(OH) 2(aq)) is a strong base. Weak acids do not completely dissociate into their ions in water. When CH 3 COONa is put in water, it completely ionises to give CH 3 COO-(acetate) ions and Na + ions. An aqueous solution of acetic acid (ethanoic acid), CH 3 COOH (aq), is an example of a weak acid. The issue is similar with bases: a strong base is a base that is 100% ionized in solution. 4)The strong acid also has a pH of 7 at its equivalence point since once the base equals the acid the solution has been neutralized and Cl- is unable to pull H off of H2O to form OH-. Weak Acid Strong Base Titration The titration of 50.0mL of 0.100M HC 2 H 3 O 2 (Ka=1.8 x 10 -5 ) with 0.100M NaOH is carried out in a chemistry laboratory. Arrhenius suggested that; a) Acid is a substance that ionizes in water to give H+ions Hydrogen chloride ionizes in water to give hydrogen (H+). A strong acid is one that dissolves in water. Ammonia is an example of a weak base as it does not completely dissolve forming ammonium and hydroxide ions. A weak acid or a weak base only partially dissociates. Some of such salts are : CH 3 COONa, Na 2 CO 3, K 2 CO 3, KCN etc .For our discussion, we consider CH 3 COONa (sodium acetate) in water. When an ionic compound dissolves, it separates into its constituent ions: \[\ce{Ca(OH)2 → Ca^{2+}(aq) + 2OH^{−}(aq)} \nonumber\]. 5. HCl, NaOH). Depending on the number of a proton the acid gives, it can be classified as mono, di, tribasic acid. The reason is that sulfuric acid is highly corrosive, while acetic acid is not as active. If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular, and the pH shifts less with small additions of titrant near the equivalence point. Distinguishing Between Strong and Weak Acids, Strong and Weak Vs. This page explains the terms strong and weak as applied to acids. Any acid that dissociates 100% into ions is called a strong acid. However, acids can be very different in a very important way. On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. We can find this acid easily although not in … Start studying strong/weak acids/bases. Weak Acid - Strong Conjugate Base Pair. Each mole of sodium hydroxide dissolves to give a mole of hydroxide ions in solution. It is important that you don't confuse the words strong and weak with the terms concentrated and dilute.. As you will see below, the strength of an acid is related to the proportion of it which has reacted with water to produce ions. NH4Cl(aq) → Cl−(aq) + NH4+(aq) Ammonium ions thus formed then interacts with the hydroxyl ions in the water molecule to form ammonium hydroxide. As a part of this it defines and explains what is meant by pH, K a and pK a.. There are only 7 common strong acids. Be careful not to confuse the terms strong and weak with concentrated and dilute. Examples of strong acids and bases are given in the table below. Most organic acids are weak acids. The relative strengths of conjugate acid-base pairs. All of the reactant (acid) is ionized into product. Example \(\PageIndex{1}\): Identifying Strong and Weak Acids and Bases. If you have 12 M acetic acid, it's concentrated, yet still a weak acid. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. The issue is similar with bases: a strong base is a base that is 100% ionized in solution. "Acidity of strong acids in water and dimethyl sulfoxide". Because Mg(OH) 2 is listed in Table 12.2 “Strong Acids and Bases” , it is a strong base. Because HCl is listed in Table 12.2 “Strong Acids and Bases”, it is a strong acid. A weak acid is an acid that doesn't produce many hydrogen ions when in aqueous solution. Explaining the term "strong base" A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. For titrations involving weak acids or weak soluble bases (weak alkalis) things are a bit more complicated. Except for their names and formulas, so far we have treated all acids as equals, especially in a chemical reaction. HCl-Hydrochloric acids; Nitric Acid-HNO3; Sulfuric Acid-H2SO4; 3 Weak Acids Also, we run into a bit of a technicality in the language. In addition to the strong Arrhenius bases, there are also superbases. strong base: A strong base is a basic chemical compound that is able to deprotonate very weak acids in an acid-base reaction. Also, we run into a bit of a technicality in the language. The back reaction is more favorable than the forward reaction, so ions readily change back to weak acid and water. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. Write the balanced chemical equation for the dissociation of hydrazoic acid (HN3) and indicate whether it proceeds 100% to products or not. All strong bases are OH– compounds. There are very few strong acids, so one of the easiest ways to tell strong and weak acids apart is to memorize the short list of strong ones.
