Galvanization is applying a coating of:

(A)Cr
(B)Cu
(C)Zn✓ Correct
(D)Pb

Answer: (C)

Solution

Galvanisation coats iron or steel with zinc. The zinc not only covers the surface but, being more reactive, corrodes in preference to the iron as a sacrificial anode, protecting it even where the coating is scratched. The metal applied is zinc.
