3.

Consider the following general reaction, at room temperature:

HClO₂ (aq) + H₂O (l) ⇌ H₃O⁺(aq) + ClO₂^–(aq) K_a = 1.2 x 10^-2

Initially, a reaction contained 0.100 M HClO₂ then it reached equilibrium. Set up an ICE table to calculate the [H₃O⁺(aq)]. Using the “x is small approximation”, which of the following best describes the calculated percentage change in the initial amount of acid?

A) 3.46%

B) 34.6%

C) 12.0%

D) 28.9%
