Question

The reactions that take place between anode and cathode are?

Answer 1

Electrolytic reduction

Answer 2

Answer :

The reactions that take place between anode and cathode are oxidation - reduction .

Electrochemic cells flow from the end to the cathode electrons because they move from one substance to another. Chemical reaction in which the electrons are transferred, called oxidation-deficiency. Oxidizing substances are losing electrons and they obtain electrons from the substance. Therefore, oxidation occurs on the underside where the electron is lost, and the deficiency is on the cathode where electrons are found.

Two beaker anodes and cathode indicate half the cells. On the left side there is a zinc in the beaker, which is oxidized. The electron passes through the outer circuit to the cathode, where the Cu2 + ion receives electrons and plates as a low density on the copper strip. The Keno 3 Salt Bridge is the source of positive and negative electrons which flows to keep charging in every half cell. For example, to balance the lost electron, the nos 3-ion anode goes into the semi-cell. Voltaic meter shows that the electron flows into the circuit.

Here are half the responses on each electrode :

$Anode(Oxidation):Zn->Zn^{2+}+2e^{-}\\Cathode(Reduction):Cu->Cu^{2+}+2e^{-}$
