Given that the K_a for HOCl is 3.5 * 10^-⁸, calculate the K value for the reaction of HOCl with OH^-. A) 3.5 * 10^-²² B) 3.5 *10^-⁸ C) 2.9 * 10^-⁷ D) 3.5 * 10⁶ E) none of these

Question

The reaction of HOCl with OH⁻ is the reverse of the dissociation of HOCl. The equilibrium constant for the reverse reaction is K_w / K_a, where K_w is the ion-product constant of water (1.0 x 10⁻¹⁴). Thus, K = 1.0 x 10⁻¹⁴ / 3.5 x 10⁻⁸ = 3.5 x 10⁶.
