What is an electrolytic cell?
An electrolytic cell converts electrical energy into chemical energy or vice versa.
Electrolytic cells use electrical energy to initiate an oxidation-reduction reaction that would not spontaneously occur otherwise.
The anode is the side of the oxidation reaction and is positively charged.
Electrolytic cells are used to electroplate metals, recharge batteries, and separate compounds like water.
Hence, option B is correct.
