Chapter 18, Problem 13E

Interpretation Introduction

Interpretation: The time required for the production of $\text{1}\text{.00}\times {\text{10}}^3\text{ kg}$ magnesium metal by electrolysis process should be determined in which molten magnesium chloride uses a current of $\text{5}\text{.00}\times {\text{10}}^4\text{ A}$ .

Concept introduction: The decomposition of a compound by passing electricity is known as electrolysis. During this process, the time required, $\text{t}$ is calculated by the formula:

  $\text{t = }\frac{\text{m}\times \text{n}\times \text{F}}{\text{I}\times \text{w}}$

Where m is mass, n is number of electrons, F is Farady’s constant, w is atomic weight of the deposited element, and I is the current.
