At the anode, the copper anode itself dissolves (dissolution), or go into solution as represented by the equation:
\(Cu _{(s)} \rightarrow Cu _{\left(a_{q}\right)}^{2+}+2 e^{-}\)(dissolution)t the cathode, \(Cu ^{2+}\) and \(H ^{+}\)are present but \(Cu ^{2+}\), being lower in the activity series, discharges in presence to \(H ^{+}\). That copper is deposited (deposition) on the copper cathode, as represented below:
$$u _{(a)}^{2+}+2 e^{-} \rightarrow C u_{(s)} \text { (deposition) }
$$
