Question

How does the metal used for galvanization prevent the rusting of iron ​

Answer 1

Answer:

Galvanizing protects from rust in a number of ways: It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. ... The zinc protects its base metal by corroding before iron. The zinc surface reacts with the atmosphere to form a compact, adherent patina that is insoluble in rainwater.
