Chapter 16, Problem 16.51QP

Interpretation Introduction

Interpretation: The value of $\left[{\text{H}}_3{\text{O}}^{+}\right]$ in a $0.125\text{M}$ solution is given to be $4.07\times {10}^{-3}\text{M}$. The degree of ionization and the equilibrium constant, $K_{\text{a}}$ of acid is to be calculated.

Concept introduction: The degree of ionization is the term that is used to express the extent of the number of ions, when the compound dissolves in a solution. The equilibrium constant helps to find out the association between concentration of reaction and product at equilibrium point.

To determine: The degree of ionization and equilibrium constant of acid.
