Chapter 12, Problem 12.9P

(a)

Interpretation Introduction

Interpretation:

Ionic strength of $\text{0}{\text{.2 mM KNO}}_{\text{3}}$ solution has to be calculated.

Concept Introduction:

Expression to compute ionic strength is as follows:

  $\text{μ}=\frac{1}{2}{\displaystyle \sum c_i{z}_i^2}$

Here

$z$ denotes charge.

$c_i$ denotes concentration.

$\text{μ}$ denotes ionic strength.

(b)

Interpretation Introduction

Interpretation:

Ionic strength of $\text{0}{\text{.2 mM Cs}}_2{\text{CrO}}_4$ solution has to be calculated.

Concept Introduction:

Refer to part (a).

(b)

Interpretation Introduction

Interpretation:

Ionic strength of mixture of $\text{0}{\text{.2 mM MgCl}}_2$ and $\text{0}{\text{.3 mM AlCl}}_3$ solution has to be calculated.

Concept Introduction:

Refer to part (a).
