Chemistry - Electrochemistry Question with Solution | TestHub

According to Faraday's first law of electrolysis:

$m=\frac{E\times I\times t}{96500}$

Here, $m=5.4\text{g}$, $I=2\text{A}$, and equivalent weight of Ag, $E=\frac{108}{1}=108{\text{g eq}}^{-1}$.

Substituting the values:

$5.4=\frac{108\times 2\times t}{96500}$

$t=\frac{5.4\times 96500}{108\times 2}$

$t=2412.5\text{s}$

Converting time into minutes:

$t=\frac{2412.5}{60}\text{min}\approx 40.2\text{min}$

Answer: $40.2\text{min}$.
