Chapter 16, Problem 16B.5AE

Interpretation Introduction

Interpretation:

The drift speed of the ${\text{Rb}}^{+}$ ion when its mobility in aqueous solution has found to be $7.92\times {10}^{-8}{\text{m}}^2{\text{s}}^{-1}{\text{V}}^{-1}$ is to be calculated.

Concept introduction:

The charged species like electrons achieve the average speed in a material owing to an electric field.  This average speed is called drift speed.  It displays a direct relationship with the current and is achieved using the formula shown below.

  $s=u\times \frac{\Delta \varphi }{l}$
