Chapter 13, Problem 177CP

Interpretation Introduction

Interpretation: The volume and concentration of ${\text{NH}}_{\text{3}}$ is given. The concentration of $\left[{\text{OH}}^{-}\right]$ is to be calculated if known concentration of solid $\text{NaOH}$ is added into ${\text{NH}}_{\text{3}}$.

Concept introduction: The equilibrium constant $K_{\text{b}}$ is the ratio of product of equilibrium concentrations of product to the equilibrium concentration of reactant base.
