Chapter 16, Problem 16.9QP

Interpretation Introduction

Interpretation:

The ion-product constant for water has to be defined.

Concept Introduction:

Water is a poor electrolyte. So it ionizes to a very small extent and it is known as auto-ionization of water. The expression of the rate constant for auto-ionization is known as the ion-product of water which is shown below:

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