Chapter 15, Problem 9E

Interpretation Introduction

Interpretation:

The given acids are to be classified as strong or weak and an expression for the acid ionization constant $\left(K_{\text{a}}\right)$ for weak acid is to be stated.

Concept introduction: Strong acids completely dissociate into an aqueous solution.
The examples of strong acids are ${\text{HNO}}_{\text{3}}$ , $\text{HCl}$ and ${\text{H}}_{\text{2}}{\text{SO}}_4$ .
The weak acids do not completely dissociate into an aqueous solution. Example, ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$ .

To determine: The classification of the given acids as strong or weak and an expression for the acid ionization constant $\left(K_{\text{a}}\right)$ for weak acid.
