Chapter 17, Problem 69E

Interpretation Introduction

Interpretation:

The reason for preferring $\text{pH}$ scale by chemists to express hydrogen ion concentration is to be stated. Advantage of saying $\text{pH}=\text{4}$ rather than $\left[{\text{H}}^{\text{+}}\right]={10}^{-4}\text{M}$ is to be stated.

Concept introduction:

Concentration of a species can be expressed in different ways. $\text{pH}$ is use to express hydrogen ion concentration in a solution. Logarithm of base $10$ is written as $\text{p}$. Value of $\text{pX}$ is written as $-{\log }_{10}\text{X}$
