Chapter 15, Problem 15.7P

Interpretation Introduction

Interpretation:

The $\text{pH}$ value for the given $\text{0}\text{.010}\text{M}$ nitrous acid $\left({\text{HNO}}_{\text{2}}\right)$ solution is to be calculated.

Concept introduction: The $\text{pH}$ value determines whether a given solution is acidic, basic or neutral in nature.

The $\text{pH}$ value is calculated by the formula,

$\text{pH}=-\log \left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$

To determine: The $\text{pH}$ value for the given $\text{0}\text{.010}\text{M}$ nitrous acid $\left({\text{HNO}}_{\text{2}}\right)$ solution.
