Chapter 16, Problem 16.10QP

Interpretation Introduction

Interpretation:

Equation relating ${\text{[H}}^{\text{+}}\text{]}$ and ${\text{[OH}}^{\text{-}}\text{]}$ in a solution at $\text{25 }°\text{C}$ has to be written.

Concept Introduction: Autoionization of water is the reaction in which the water undergoes ionization to give a proton and a hydroxide ion.  Water is a very weak electrolyte and hence it does not completely dissociate into the ions.  The ionization happens to a very less extent only.  The ionization of water is an equilibrium reaction and hence this has equilibrium rate constant.

$K_w=[{\text{H}}^{+}][{\text{OH}}^{-}]=1.0\times {10}^{-14}$
