Chapter 18.3, Problem 18.4BFP

Interpretation Introduction

Interpretation: $\left[{\text{OH}}^{-}\right]$ concentration must be found out. From the concentration of $\text{[H}\text{O}{}^{\text{+}}\text{]}$ , the nature of the solution, whether acidic, basic, or neutral, must be identified.

Concept introduction: The pH scale will range from 1-14. pH is the negative logarithm of hydrogen ion concentration. The ionic product of water is the product of ${\text{[OH}}^{\text{-}}\text{]}$ and $\text{[H}\text{O}{}^{\text{+}}\text{]}$ concentrations at $\text{25°C}$ .

  $K\text{=}\left[{\text{OH}}^{-}\right]\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$

  $K$ = $1.0\times {10}^{-14}$ at $\text{25°C}$
