Question

2
metal is used to prevent corrosion of iron.​

Answer 1

Answer:

The corrosion-prone iron alloy steel is commonly coated with zinc, a more active metal, in a process known as galvanizing. Corrosion of the sacrificial zinc results in its oxidation; the iron is reduced, which renders it cathodic and inhibits its corrosion.

Answer 2

One simple way to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. Depending on the application, these metals can be used to reduce the need for additional corrosion protection
