HSO − 4 (aq) + H 2O(l) ⇌ H 3O + (aq) + SO2 − 4 (aq) with Ka2 = 1.2 × 10 − 2. This stepwise ioniza tion process occurs for all polyprotic acids. When we make a solution of a weak diprotic acid, we get a solution that contains a mixture of acids. Carbonic acid, H 2CO 3, is an example of a weak diprotic acid. A polyprotic acid H N A is a molecule with N proton-binding sites. Each site is capable of binding 1 proton; the corresponding site-variable has two states: α i = 0 (empty) and 1 (occupied). In total, there are 2 N microstates α (ν) = (α 1, α 2, … α N), which form a statistical ensemble.HSO 3– ( aq) + H 2 O ( l) ⇆ SO 32- ( aq) + H 3 O + ( aq ) Ka2 = 6.4 x 10-8. When titrated with a base, one of the protons reacts with the hydroxide first to form the conjugate base HSO 3–, which then reacts with the base forming the SO 32- conjugate base. Let’s say we are titrating 25.0 mL of 0.100 M H2SO3 with 0.100 M NaOH.The mathematical description of polyprotic acids (with N ≥ 3) is a special topic that extends the traditional view on acid-base reactions.

Citric acid is commonly used as a buffer for this pH region. It is also worth examining what would be observed for a similar plot of a different triprotic acid. The data in Table 5 is for an identical titration of phosphoric acid.This stepwise ioniza tion process occurs for all polyprotic acids. When we make a solution of a weak diprotic acid, we get a solution that contains a mixture of acids. Carbonic acid, \(\ce{H2CO3}\), is an example of a weak diprotic acid.
