In electrolytic cell reduction occurs at anode and in galvanic cell oxidation takes place at anode.

Vedclass · Answer

(B) Let us analyze each statement:$A$: Mercury cell is a primary cell that provides a constant potential of approximately $1.35 \ V$ throughout its life. This is a correct statement.$B$: In an electrolytic cell,reduction occurs at the cathode and oxidation occurs at the anode. In a galvanic cell,oxidation also occurs at the anode. However,the statement claims reduction occurs at the anode in an electrolytic cell,which is incorrect.$C$: Galvanised iron is coated with a layer of zinc. Zinc acts as a sacrificial anode and prevents the iron from rusting. This is a correct statement.$D$: During the recharging process,a lead storage battery acts as an electrolytic cell where electrical energy is converted into chemical energy. This is a correct statement.Therefore,the incorrect statement is $B$.

Which of the following is an incorrect statement?
