Chapter 14, Problem 46E

Interpretation Introduction

(a)

Interpretation:

The hydroxide ion concentration is to be calculated.

Concept introduction:

Pure water is not a very good conductor of electricity due to the presence of a very small number of ions that are responsible for the flow of electricity. This happens very rarely that two water molecules collide with the appropriate amount of energy to give back hydronium ion ${\text{H}}_{\text{3}}{\text{O}}^{+}$ and hydroxide ion ${\text{OH}}^{-}$.
