Chapter 21, Problem 108SCQ

a)

Interpretation Introduction

Interpretation: Number of kilowatt hours of energy required to produce $\text{1}\text{.00kg}$ of chlorine needed to be predicted and the mass of the sodium need to calculated for $\text{1-hour}$ passage of charge during the electrolysis of molten sodium chloride.

Concept introduction:

Charge of the electrode is defined as the product of the current passed through the electrode and time it has taken to pass that electrode.

$\begin{array}{c}\text{charge}\text{=}\text{current×time}\\ \text{Q}\text{=}\text{i×t}\end{array}$

Potential of the electrode is defined as the ratio of potential energy to the charge at that electrode.

$\begin{array}{c}\text{potential}\text{=}\frac{\text{potential energy}}{\text{charge}}\\ \text{V}\text{=}\frac{\text{E}}{\text{Q}}\end{array}$
