Chapter 14, Problem 7ST

Interpretation Introduction

Interpretation:

The molar hydroxide ion concentration of an aqueous solution in which the $\left[{\text{H}}^{\text{+}}\right]=2.5\times {10}^{-7}$ is to be identified.

Concept introduction:

The $\text{pH}$ of the solution is defined as the power of hydrogen ions and is equal to the negative logarithm of hydrogen ion concentration. The acidic solutions have $\text{pH}$ less than $7$ and basic solutions have the $\text{pH}$ greater than $7$.
