Question

Mr Ramu wants to electroplate his key chain with nickel to prevent rusting. For this electroplating
(i) Name the Electrolyte.
(ii) Name the cathode.
(iii) Name the anode.
(iv) Give the reaction at the cathode.
(v) Give the reaction at the anode.​

Answer 1

)(i)Nickel sulphate solution(NiSO4)

(ii) Key chain

(iii)Pure nickel block

(iv) At the cathode: Ni+2 + 2e- →

) At the cathode: Ni+2 + 2e- →Ni

(v) At the anode: Ni - 2e- → Ni+2

(b)Electroplating is a process in which a thin film of a metal like gold, silver, nickel, chromium, etc. gets deposited on another metallic article with the help of electricity
