Chapter 8, Problem 8.62E

Interpretation Introduction

(a)

Interpretation:

The ionic strengths for intra- and extracellular fluids are to be stated.

Concept introduction:

The ionic strength is calculated 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 $i^{\text{th}}$ 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 reason as to how the overall ionic charge is balanced when concentration of cations is not equal to the concentration of anions is to be stated.

Concept introduction:

The ionic strength is calculated 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 $i^{\text{th}}$ 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.
