Electroplating explanation

Question

In electroplating, the copper metal terminal is ....

Answer 1

The copper metal terminal is the anode.

Oxidation takes place at the anode. Thus, Cu metal is the anode and becomes oxidized to Cu²⁺. This ion combines with SO4^2- in solution, and then the Cu²⁺ is reduced at the cathode to be plated as solid Cu on the cathode.
