Question

During electroplating a copper spoon with silver :

(I) Give three dissociation reactions.
(ii) Give the reaction at anode and cathode.
(iii) Give three conditions required for electroplating.
(iv) Give two applications of electrolysis.​

Answer 1

Answer:

Silver plating on Steel spoon: A silver rod is made as anode and steel spoon as cathode. Potassiumargentocyanide (K[Ag(CN)2]) is used as electrolyte.

AgNO3 is not used as electrolyte because in that case the silver coating will be non-uniform as the electrolysis takes place rapidly.

In electroplating of copper by silver, silver rod is taken as anode.
