Chapter 16, Problem 16.38QP

Interpretation Introduction

Interpretation: The $\text{pH}$ of a $6.9\times {10}^{-8}\text{M}$ solution of $\text{HBr}$ is to be calculated.

Concept introduction: The potential of ${\text{H}}^{\text{+}}$ ions is called as $\text{pH}$ and the potential of ${\text{OH}}^{-}$ ions is called as $\text{pOH}$. The value of $\text{pH}$ is less than $7$ for acidic solutions and greater than $7$ for basic solutions. For neutral solution the value of $\text{pH}$ is $7$.

To determine: The $\text{pH}$ of a $6.9\times {10}^{-8}\text{M}$ solution of $\text{HBr}$.
