We regret the misprint of two chemical equations in the original article.

The correct equations of the equilibria are as follows:

Equilibrium 10

$${{\text{H}}_2}{{\text{A}}^+}{\text{ }}+{\text{ }}{{\text{H}}_2}{\text{O }} \rightleftarrows {({\text{H}}{{\text{A}}^ \pm })_x}{\text{ }}+{\text{ }}{({\text{HA}})_{1 - x}}{\text{ }}+{\text{ }}{{\text{H}}_3}{{\text{O}}^+}$$

Equilibrium 11

$${({\text{H}}{{\text{A}}^ \pm })_x}{\text{ }}+{\text{ }}{({\text{HA}})_{1 - x}}{\text{ }}+{\text{ }}{{\text{H}}_2}{\text{O }} \rightleftarrows {\text{ }}{{\text{A}}^ - }{\text{ }}+{\text{ }}{{\text{H}}_3}{{\text{O}}^+}.$$
