Question

In order to obtain a coating of silver on copper, the cathode, anode and electrolyte have to be

A) copper silver, silver nitrate solution

B) copper silver.copper nitrate solution

Csilver copper silver nitrate solution

D) silver, copper ,copper sulphate solution​

Answer 1

In order to obtain a coating of silver metal on a flower vase made of copper, the electrolyte has to be A. silver nitrate solution. Explanation: The silver metal is taken as anode whereas copper metal is taken as cathode.

Answer 2

Answer:

$\huge{ Answer }{\heartsuit}$

Different masses of Cu and Ag will be deposited at cathode. According to Faraday,s second law of electrolysis amount of different substance liberated by same quantity or electricity passes through electrolyte solution is directly proportional to their chemcial equivalent weight.

W1W2=E1E2

where, E1 and E2 have different values depending upon number of electrons required to reduce the metal ion. thus, massess of Cu and Ag deposited will be different.
