Chapter 12, Problem 12.14P

(a)

Interpretation Introduction

Interpretation:

Concentration of ${\text{Ag}}^{+}$ in $\text{AgSCN}$ in presence of $\text{0}{\text{.06 M KNO}}_3$ has to be calculated.

Concept Introduction:

Extended Debye Huckel law quantifies activity coefficient in terms of ionic strength and hydrated size as follows:

  $\log \text{γ}=\frac{-0.51z^2\sqrt{\text{μ}}}{1+\left(\text{α}\sqrt{\text{μ}}\text{/}305\right)}$

Here

$z$ denotes charge.

$\text{μ}$ denotes ionic strength.

$\text{γ}$ denotes activity coefficient.

$\text{α}$ denotes ionic size.
