Chapter 17, Problem 130AE

Interpretation Introduction

Interpretation:

The reason behind the absence of $+1$ charge over the given metal for a given amount of metal that is deposited when a given amount of current is passed for a certain period of time is to be stated.

Concept introduction:

The non-spontaneous reaction takes place in an electrolytic cell in which there occurs conversion of electrical energy into chemical energy and this is used for the electrolysis of a metal.

The charge generated in the cell is calculated as,

$Q=It$

When electricity is passed through an electrolytic cell, at that time the amount of the substance that is liberated at an electrode is given by,

$\begin{array}{c}W=ZQ\\ =ZIt\end{array}$

The value of $Z$ is given as,

$Z=\frac{\text{Molar}\text{mass}}{n\times 96,485}$

To determine: The reason behind the absence of $+1$ charge over the given metal for a given amount of metal that is deposited when a given amount of current is passed for a certain period of time.
