Question

Explain the electroplating of silver on a copper spoon
by taking silver nitrate(AgNO3) solution

Answer 1

Explanation:

Suppose we have a Ag(NO3) solution.

and we take a copper spoon at the cathode and silver bar in the anode as electrodes. What will happen when we pass the current through the solution?

The Ag(NO3) solution dissociates to form Ag+ and NO3- . The Ag+ ions will move towards the cathode and there it picks up 1 electron from copper spoon and gets deposited. At the same time the silver bar gradually dissolves to replace the Ag+ ions in the solution. This process continue until the whole silver bar dissolves in the solution and you get a layer of coating over copper spoon.

Answer 2

Answer:

Here, silver nitrate is used as the electrolyte. Turn on the Circuit. ... When electric current flows through the set up, pure Silver from anode disassociated and gets deposited in the copper spoon, i.e. Cathode. Hence, we got the electroplated copper spoon.
