- Through a process known as hydrolysis, the ions produced when an acid and base combine may react with the water molecules to produce a solution that is slightly acidic or basic. As a general concept, if a strong acid is mixed with a weak base, the resulting solution will be slightly acidic.

Titration curves for weak acid v weak base The common example of this would be ethanoic acid and ammonia. It so happens that these two are both about equally weak - in that case, the equivalence point is approximately pH 7.
Acids can be either strong or weak, depending on how many ions they produce when they dissolve in water. When added to water, acids ionise or dissociate to produce H + ions. For example, the general acid HX dissociates to form H + and X –. HX H+ + X–.
Ethanoic acid is a weak acid which ionises as follows: CH 3 COOH (aq) ⇌ H + (aq) + CH 3 COO- (aq) Step 1: Write down the equilibrium expression to find K a. Step 2: Simplify the expression. The ratio of H + to CH 3 COO- ions is 1:1. The concentration of H + and CH 3 COO- ions are therefore the same. The expression can be simplified to:
Jul 12, 2023 · In an acid–base reaction, the proton always reacts with the stronger base. For example, hydrochloric acid is a strong acid that ionizes essentially completely in dilute aqueous solution to produce \(H_3O^+\) and \(Cl^−\); only negligible amounts of \(HCl\) molecules remain undissociated.
Jul 4, 2022 · Conversely, strong bases react completely with water to produce the hydroxide ion, whereas weak bases react only partially with water to form hydroxide ions. The reaction of a strong acid with a strong base is a neutralization reaction, which produces water plus a salt.
