Chapter 8, Problem 8.6P

Interpretation Introduction

Interpretation:

The activity coefficient of ${\text{H}}^{\text{+}}$ ion has to be calculated.

Concept introduction:

Extended Debye-Huckel equation:

The relationship between activity coefficient and the ionic strength is given by extended Debye-Huckel equation.

$\begin{array}{l}\text{log}\text{γ}\text{=}\frac{\text{-}\text{0}\text{.51}{\text{z}}^{\text{2}}\sqrt{\text{μ}}}{\text{1}\text{+}\left(\text{α}\sqrt{\text{μ}}\text{/305}\right)}\\ \text{where,}\\ \text{γ}\text{-}\text{activity}\text{coefficient}\text{of}\text{ion}\\ \text{μ}\text{-}\text{ionic}\text{strength}\text{of}\text{solution}\\ \text{α}\text{-}\text{size}\text{of}\text{ion}\end{array}$
