Chemistry - Electrochemistry Question with Solution | TestHub

When electric current is passed through an electrochemical cell, the cell reaction is completely reversed i.e., reduction takes place at anode and oxidation takes place at cathode. Therefore, in the electrochemical cell $\mathrm{Zn}\left|{\mathrm{Zn}}^{2+}\Vert {\mathrm{Cu}}^{2+}\right|{\mathrm{Cu}}^{2+}\mid \mathrm{Cu},{\mathrm{Zn}}^{2+}$ will be reduced to Zn and Cu will be oxidised to ${\mathrm{Cu}}^{2+}$ ions.
