Question

According to Faraday's law of electrolysis, the amount of deposition is proportional to

• A. $\frac{1}{\text{time for which current passes}}$
• B. $\text{electrochemical equivalent of substance}$
• C. $\frac{1}{\text{current}}$
• D. $\frac{1}{\text{electrochemical equivalent}}$

Answer 1

The correct option is B $\text{electrochemical equivalent of substance}$

According to Faraday's law of electrolysis, the amount of deposition is $m=zIt$

where $z=$ electrochemical equivalent, $I=$ current and $t=$ time for current passes. Thus, $m\propto z$
