Chapter 16, Problem 144AP

Interpretation Introduction

Interpretation:

The value of pD for which the solution will be acidic and the relationship between pD and pOD, for ${\text{D}}_2\text{O}$, are to be determined.

Concept introduction:

Acids and bases react together to neutralize each other and form their conjugate bases and conjugate acids, respectively.

$\text{Acid}+\text{Base}\rightleftharpoons \text{conjugate base}+\text{conjugate acid}$

Water is a universal solvent and a very weak electrolyte that undergoes ionization to a very small extent.

${\text{2H}}_2{\text{O}}_{\left(\text{l}\right)}\rightleftharpoons {\text{H}}_3{\text{O}}^{+}{}_{\left(\text{aq}\right)}+{\text{OH}}^{-}{}_{\left(\text{aq}\right)}$

$K_{\text{w}}=\left[{\text{H}}_3{\text{O}}^{+}\right]\left[{\text{OH}}^{-}\right]$ …… (1)
