Question

please give answer quickly I request you kindly because tomorrow will my exam​

Answer 1

Answer:

(a) Which process will you study with the diagram?

Ans:- Electroplating.

(b) Define the process.

Ans:- The process in which a less reactive metal is coated on a more reactive metal by electrolysis is called Electroplating.

Eg. Silver-plated spoon, gold-plated jewellery.

(c) Explain the process in brief.

Ans:- 1) The electroplating process uses an anode and a cathode.

2) In electroplating, the metal dissolved from the anode can be plated onto the cathode.

3) The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution.

4) At the cathode, the dissolved metal ions are decreased and the metal is placed on the product.

(d) Write the anode and cathode reactions.

Ans:- Anode: Cu(s) → Cu2+(aq) + 2 e-

Cathode: Cu2+(aq) + 2 e- → Cu(s)

I hope this will help you

Answer 2

Answer:

1. it's electroplating method

on it less reactive metal is coated on surface with electrolysis to control corrosion of metals

for eg silver plated spoons ,etc

cu =cu2+. + 2e- cathode

cu2+ + 2e-=Cu- anode

cu. +2agno3. = cu(no)3+2ag
