Electroplating saves:

Question

Electroplating saves:

1. A. The metal from corrosion (Correct answer)
2. B. The plastic from melting
3. C. Clothes from ironing
4. D. None of the above

Correct Answer

Option A — The metal from corrosion

Detailed Solution & Explanation

The correct answer is The metal from corrosion.

Key Points

• Electroplating deposits a thin layer of one metal onto another by electrolysis, chiefly to protect the base metal from corrosion.
• The object to be plated is made the cathode, and the plating metal forms the anode.

Additional Information

• Everyday examples: chromium plating on car parts and taps, zinc on iron (galvanisation), tin on iron food cans, and silver or gold on jewellery.
• Plating also improves appearance, hardness and electrical conductivity, but corrosion resistance is the primary purpose.
• Rusting specifically affects iron and needs both oxygen and moisture; excluding either prevents it, which is what a plated layer achieves.
