Chapter 17, Problem 73IAE

The neutralization of NaOH 2by HCl is represented in equation (1), and the neutralization of ${\text{NH}}_2$ by HCl in equation (2).

A. ${\text{OH}}^{\text{-}}+{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\rightleftharpoons 2{\text{H}}_{\text{2}}\text{O}K\text{=?}$

B. ${\text{NH}}_{\text{3}}{\text{+H}}_{\text{3}}{\text{O}}^{+}\rightleftharpoons {\text{NH}}_{\text{4}}+{\text{H}}_{\text{2}}\text{O}K\text{=?}$

a. Determine the equilibrium constant K for each reaction.

b. Explain why each neutralization reaction can be considered to go to completion.
