Chapter 26, Problem 26.38P

(a)

Interpretation Introduction

Interpretation:

The grater electrophoretic mobility having compound should be predicted from Fumarate and Maleate.

Concept introduction:

Electrophoretic mobility:

Electrophoretic mobility is the constant of proportionality between the electric field strength and speeds of the ion.

$\begin{array}{l}{\text{u}}_{\text{ep}}\text{=}\frac{\text{q}}{\text{f}}\text{E}\\ \text{=}{\text{μ}}_{\text{ep}}\text{E}\end{array}$

Here, f is the friction coefficient.

Stokes equation for Friction coefficient is,

$\text{f=}\text{6πμr}$

Where,

$\text{q/6πμr}$ is molecular radius.

(b)

Interpretation Introduction

Interpretation:

The separation order of from Fumarate and Maleate in electrophoresis should be given.

Concept introduction:
