Chapter 23, Problem 23.10P

(a)

Interpretation Introduction

Interpretation:

The distribution coefficient expression has to be defined for the given system.

Concept introduction:

Distribution coefficient:

Distribution coefficient $\left(\text{D}\right)$ is defined as the quotient of total concentrations of solute in phases.

$\text{D=}\frac{\text{Total}\text{concentration}\text{in}\text{phase}\text{2}}{\text{Total}\text{concentration}\text{in}\text{phase}\text{1}}$

(b)

Interpretation Introduction

Interpretation:

The difference between $\text{D}\text{and}\text{K}$ has to be given.

(c)

Interpretation Introduction

Interpretation:

The value of distribution coefficient $\left(\text{D}\right)$ has to be calculated.

Concept introduction:

Distribution coefficient:

Distribution coefficient $\left(\text{D}\right)$ is defined as the quotient of total concentrations of solute in phases.

$\text{D=}\frac{\text{Total}\text{concentration}\text{in}\text{phase}\text{2}}{\text{Total}\text{concentration}\text{in}\text{phase}\text{1}}$

(d)

Interpretation Introduction

Interpretation:

The value of distribution coefficient $\left(\text{D}\right)$ will be greater or less at pH 10.00 than at pH 8 has to be checked.

Concept introduction:

Distribution coefficient:

Distribution coefficient $\left(\text{D}\right)$ is defined as the quotient of total concentrations of solute in phases.

$\text{D=}\frac{\text{Total}\text{concentration}\text{in}\text{phase}\text{2}}{\text{Total}\text{concentration}\text{in}\text{phase}\text{1}}$
