Chapter 17, Problem 17.31P

Interpretation Introduction

Interpretation:

The percentage of cadmium ion which can be reduced in polarogram has to be determined.

Concept introduction:

At any point in an electric circuit the charge q is the product of current I and time t.

$\text{q}\text{=}\text{I}·\text{t}$

The number of moles of electrons n reacts in a reaction with given time t is

$\text{Reacted}\text{moles}\text{=}\frac{\text{I}\text{.}\text{t}}{\text{nF}}$
