Chapter 14, Problem 83E

Interpretation Introduction

Interpretation:

For each of the given solution, the $\text{pH}$ of the solution is to be determined from the given $\text{pOH}$ values and based on the $\text{pH}$ value, each solution is to be classified as acidic, basic or neutral.

Concept introduction:

The sum of $\text{pH}$ and $\text{pOH}$ in a solution is always equals to $14$ at a constant temperature. At ${25}^{°}\text{C}$, mathematically it can be shown as follows:

$\text{pH}+\text{pOH}=\text{14}\text{.0}$

The $\text{pH}$ scale is used to classify whether the solution is acidic or basic. The three points for the solution are as follows:

The solution with $\text{pH}$ value less than 7 is acidic.

The solution with pH value greater than 7 is basic.

If the solution with pH equals to 7 is neutral.
