Chapter 17, Problem 54E

Interpretation Introduction

Interpretation:

The values of $\text{pOH}$, $\left[{\text{H}}^{+}\right]$, and $\left[{\text{OH}}^{-}\right]$ of a solution with $\text{pH}=4$ are to be predicted. Whether the solution is strongly acidic, weakly acidic, neutral, weakly basic or strongly basic is to be predicted.

Concept introduction:

The $\text{pH}$ scale tells about the strength of an acid and a base. It measures the concentration of the hydrogen ions. There is an inverse relation between the $\text{pH}$ value and the concentration of the hydrogen ion. Higher the concentration of hydrogen ions, lesser the value of $\text{pH}$. There is an inverse relation between the $\text{pOH}$ value and the concentration of the hydroxide ion. Higher the concentration of hydroxide ions, lesser the value of $\text{pOH}$.
