Detailed explanation-1: -Reduction occurs at cathode both in galvanic as well as in electrolytic cell . In electrolytic cell cathode is the negative electrode and in the galvanic cell cathode is the positive electrode. Similarly oxidation occurs at anode both in galvanic as well as in electrolytic cell.
Detailed explanation-2: -During electrolysis, reduction i.e., gain of electrons takes at cathode. Reason: Oxidation always take place at anode and reduction at cathode.
Detailed explanation-3: -Reduction happens at the negative cathode because this is where positive ions gain electrons. Oxidation happens at the positive anode because this is where negative ions lose electrons.
Detailed explanation-4: -Electrons act as reactants during reduction reactions in the cathode, whereas they serve as products during oxidation reactions in the anode.
Detailed explanation-5: -In an electrochemical cell, reduction takes place at anode BECAUSE oxidation always takes place at the cathode.
