Chapter 13, Problem 13.14P

Interpretation Introduction

Interpretation:

The composition of solution and fraction of iron and Glycine in each of its form and the principal chemistry required for the addition of $\text{HCl}$ to obtain $\text{pH}\text{of 8}\text{.50}$ has to be calculated. The values of $\text{pFe,pG}$ and $\text{pCl}$ that satisfy the combined charge and mass balances has to be estimated.

Concept introduction:

Davies equation:

The activity coefficient $\left(\text{γ}\right)$ of ions is given by

$\begin{array}{l}\text{log}\text{γ}\text{=}\text{-}\text{0}\text{.51}{\text{z}}^{\text{2}}\left(\frac{\sqrt{\text{µ}}}{\text{1}\text{+}\text{}\sqrt{\text{µ}}}\text{-}\text{0}\text{.3}\text{µ}\right)\\ \text{where,}\\ \text{γ}\text{-}\text{activity}\text{coefficient}\text{of}\text{ion}\\ \text{z-}\text{charge}\text{of}\text{ion}\\ \text{µ}\text{-}\text{ionic}\text{strength}\end{array}$
