Chapter 18.2, Problem 18.2BFP

Interpretation Introduction

Interpretation:

The concentration of $\left[{\text{OH}}^{-}\right]$ in the solution is to be calculated. Also, the solution is the acidic, basic and neutral is to be identified.

Concept introduction:

The solution is acidic if the concentration of the hydronium ion is greater than the concentration of the hydroxide ion in the solution.

The solution is basic if the concentration of the hydroxide ion is greater than the concentration of the hydronium ion in the solution.

The solution is neutral if the concentration of the hydroxide ion is equal to the concentration of the hydronium ion in the solution.

At $25°\text{C}$, the expression to calculate the concentration of the $\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$ is given as,

$\left[{\text{H}}_3{\text{O}}^{+}\right]\left[{\text{OH}}^{-}\right]={10}^{-14}$
