Question

If you needed to make ultrapure silver from crude silver, where would you collect the pure silver metal in an electrolytic cell?

Answer 1

In an electrolytic cell, the reduction happens on the cathode.

Explanation:

In an electrolytic cell, the reduction happens on the cathode.

Silver crude must be molten or in solution to produce the silver ion `Ag^(+)`, thus, silver can then be reduced as follows:

`Ag^(+)+1e^(-)->Ag`
