Chapter 18.4, Problem 18.5BFP

Interpretation Introduction

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

  $\text{K}\text{=}\text{[}O{H}^{-}\text{][}HO{}^{+}\text{]}$

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