Chapter 18.7, Problem 18.10AFP

Interpretation Introduction

Interpretation: Given the value of ${\text{pK}}_{\text{b}}$ , the $\text{pH}$ of the given concentration of the solution must be found out.

Concept introduction: pH is the negative logarithm of hydrogen ion concentration and it gives the nature of the solution. ${\text{pK}}_{\text{b}}$ is the negative logarithm of the base dissociation constant. Base dissociation constant gives the ratio of the concentration of the products to that of the reactants.

  ${\text{K}}_{\text{b}}\text{=}\frac{\text{[Products]}}{\text{[Reactants]}}$
