Chapter 25, Problem 25.62P

Interpretation Introduction

Interpretation:

Time required to electrodeposit $200.0\text{ mg}$ gold has to be calculated.

Concept Introduction:

Time needed to electrodeposit a metal during electrolysis can be determined using the following equation,

  $\text{m=}\left(\frac{\text{I}\text{t}}{\text{F}}\right)\left(\frac{\text{M}}{{\text{ν}}_{\text{e}}}\right)$

Here, $\text{t}$ is the total time the constant current $\left(\text{I}\right)$ is applied.

The symbol $\text{F}$ is the Faraday’s constant.

The symbol $\text{M}$ is the molar mass of the substance in grams per mol.

The symbol ${\text{ν}}_{\text{e}}$ is the number of electrons transferred.
