Chapter 16 - Acid-Base Equilibria - Exercises: 16.21c

Answer

${O_2}^{2-}$ is a strong base. Conjugate acid: $OH^-$ which has negligible acidity.

Work Step by Step

${O_2}^{2-}(aq) + H_2O(l) --> 2OH^-(aq)$ As we can observe, $OH^-$ is the conjugate acid of ${O_2}^{2-}$. Since ${O_2}^{2-}$ is a strong base, his conjugate acid will have negligible acidity.
