Chapter 14, Problem 14.112CHP

Interpretation Introduction

Interpretation:

Fraction of the molecules in liquid water, percent dissociation and $pH$ of a neutral solution at $0^{0}C$ has to be determined.

Concept introduction:

• The ion-product constant for a water is the equilibrium expression for the dissociation constant of water, given by

$K_w=[H_3{O}^{+}][O{H}^{-}]=[O{H}^{-}][H_3{O}^{+}]$

• $pH$ is used to refer to the power of 10 used to express the molar concentration of $H_3{O}^{+}$. It is given by, $pH=-\log [H_3{O}^{+}]$
