Chapter 14, Problem 9SAQ

Interpretation Introduction

Interpretation: The concentration of hydronium ion, $\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$ is to be calculated for the given concentration of hydroxide ion, $\left[{\text{OH}}^{-}\right]=2.5\times {10}^{-4}\text{M}$.

Concept Introduction:

The $\text{pH}$ of hydronium ion $\left({\text{H}}_3{\text{O}}^{+}\right)$ calculated using the relation is expressed as:

$\text{pH}=-\log \left[{\text{H}}_3{\text{O}}^{+}\right]$

The $\text{pOH}$ of hydroxyl ion $\left({\text{OH}}^{-}\right)$ calculated using the relation is expressed as:

$\text{pOH}=-\log \left[{\text{OH}}^{-}\right]$

The relation between $\text{pOH}$ and $\text{pH}$ is as:

$\text{pH}+\text{pOH}=14$
