Chapter 8, Problem 8.60E

Interpretation Introduction

(a)

Interpretation:

The ionic strength for $0.0055\text{molal}\text{HCl}$ solution is to be calculated.

Concept introduction:

The ionic strength is given by the formula given below.

$I=\frac{1}{2}{\displaystyle \sum _{i=1}^{\text{ions}}{m}_i{z}_i^2}$

In the above expression, $m_i$ is the molality of the $i$ th ion and $z_i^2$ is the square of charge on the ions. In a chemical reaction, the ionic strength is calculated as the sum of products of molality and square of charge on the ions.

Interpretation Introduction

(b)

Interpretation:

The ionic strength for $0.075\text{molal}{\text{NaHCO}}_{\text{3}}$ is to be calculated.

Concept introduction:

The ionic strength is given by the formula given below.

$I=\frac{1}{2}{\displaystyle \sum _{i=1}^{\text{ions}}{m}_i{z}_i^2}$

In the above expression, $m_i$ is the molality of the $i$ th ion and $z_i^2$ is the square of charge on the ions. In a chemical reaction, the ionic strength is calculated as the sum of products of molality and square of charge on the ions.

Interpretation Introduction

(c)

Interpretation:

The ionic strength for $0.0250\text{molal}\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ is to be calculated.

Concept introduction:

The ionic strength is given by the formula given below.

$I=\frac{1}{2}{\displaystyle \sum _{i=1}^{\text{ions}}{m}_i{z}_i^2}$

In the above expression, $m_i$ is the molality of the $i$ th ion and $z_i^2$ is the square of charge on the ions. In a chemical reaction, the ionic strength is calculated as the sum of products of molality and square of charge on the ions.
