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

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 $A {g}^{+}$, thus, silver can then be reduced as follows:

$A {g}^{+} + 1 {e}^{-} \to A g$
