Chapter 18, Problem 70E

Interpretation Introduction

Interpretation:

The ${\text{K}}_{\text{a}}$ and the percent ionization of $\text{0}\text{.48}\text{M}$ aqueous solution of nitrous acid is to be stated.

Concept introduction:

A strong acid easily releases protons to a base or when dissolved in water. It readily participates in an acid-base reaction. A weak acid undergoes only slight ionization in solution. It does not release protons easily. The major species present in a solution of weak acid is the unionized molecular species. However, some ions are present as minor species. The extent of the ionization is determined by the ionization constant.
