Chapter 18.4, Problem 18.5AFP

Interpretation Introduction

Interpretation: Given the value of pOH, the concentration of ${\text{[OH}}^{\text{-}}\text{]}$ and concentration of $\text{[H}\text{O}{}^{{}^{\text{+}}}\text{]}$ has to be found out. From the concentration of $\text{[H}\text{O}{}^{\text{+}}\text{]}$ the nature of the solution, acidic basic or neutral has to 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 ${\text{25}}^{\text{0}}\text{C}$ .

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

  ${\text{[OH}}^{-}{\text{][H}}_{\text{3}}{\text{O}}^{+}\text{]}$ = $1.0\times {10}^{-14}$ at ${\text{25}}^{\text{0}}\text{C}$ .
