Chapter 7, Problem 107E

Interpretation Introduction

Interpretation: The pH of 0.010 M solution of HB needs to be determined, if the pH of salt NaB is 9.00 for 0.050 M solution.

Concept Introduction: A base is the substance that gives ${\text{OH}}^{\text{-}}$ ions in its aqueous solution. On the basis of base dissociation, they can be classified as strong and weak base. On the contrary, a weak base ionized partially and reaches to equilibrium.

  ${\text{BOH}}_{\text{(aq)}}\rightleftharpoons {\text{OH}}^{\text{-}}{}_{\text{(aq)}}{\text{+B}}^{\text{-}}{}_{\text{(aq)}}$

An acid is the substance that gives ${\text{H}}^{+}$ ions in its aqueous solution. On the basis of acid dissociation, acids can be classified as strong and weak acid. On the contrary, a weak acid ionized partially and reaches to equilibrium.

  ${\text{HA}}_{\text{(aq)}}{\text{+ H}}_{\text{2}}{\text{O}}_{\text{(l)}}\rightleftharpoons {\text{H}}_{\text{3}}{\text{O}}^{\text{+}}{}_{\text{(aq)}}{\text{+ A}}^{\text{-}}{}_{\text{(aq)}}$
