Question

Answer is D, how come?

All of the following affect the number of moles of metal deposited during electrolysis EXCEPT the current used electrolysis time charge on the ion molar mass

Answer 1

Faraday's First Law of Electrolysis states that only, According to this law, the chemical deposition due to flow of current through an electrolyte is directly proportional to the quantity of electricity (coulombs) passed through it. i.e. mass of chemical deposition.

m $\alpha$ quantity of electricity

m = ect

Where

m = mass of metal deposited

c = current

t = time taken

Since m depends upon current used, electrolysis time & charge on the ion. But not on the molar mass

So the correct option is (D)
