(a) Define electroplating. How can steel spoons be plated with silver ?Explain
with the help of diagram.
(b)state any three uses of electroplating.
Answers
Answer:
Explanation:
→ DEFINITION OF ELECTROPLATING
⇒ Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes
→ How can steel spoons be plated with silver ?
⇒ In silver plating, the object to be plated (e.g., a spoon) is made from the cathode of an electrolytic cell. The anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of silver cyanide, AgCN, in water. This produces a shinier and more adherent silver plating.
→ Three uses of electroplating
- Improving wear resistance.
- Improving the thickness of the metal surface.
- Enhancing the electrical conductivity like plating a copper layer on an electrical component.
- Minimizing Friction.
- Improving surface uniformity.
Answer:
a.) In silver plating, the object to be plated (e.g., a spoon) is made from the cathode of an electrolytic cell. The anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of silver cyanide, AgCN, in water. ... This produces a shinier and more adherent silver plating.
b.)Uses of Electroplating
1. Aesthetics.
2. Commercial applications.
3. To prevent corrosion.
4. Conduction of Electricity.
5. Reduce friction.
6. To protect from radiation.
