Galvanization is applying a coating of :
  1. A
    Cr
  2. B
    Cu

    Pb
View written solutionFree

Correct answer: C

  1. Meaning of galvanization

    Galvanization is the process of applying a protective coating of zinc on iron or steel to prevent rusting.

  2. Why zinc is used

    • Zinc forms a protective layer over iron.
    • Even if the coating is scratched, zinc acts as a sacrificial metal and protects iron from corrosion.

  3. Evaluate the options

    • A: Cr (Chromium) → Used in chrome plating, not galvanization.
    • B: Cu (Copper) → Copper coating is not called galvanization.
    • C: Zn (Zinc) → Correct; galvanization means zinc coating.
    • D: Pb (Lead) → Not used for galvanization.

  4. Conclusion

    Therefore, galvanization is applying a coating of: Zn\boxed{\text{Zn}}Zn​
