Question

Galvanization is a process of coating iron metal with

• A. Copper
• B. Zinc
• C. Chromium
• D. Nickel

Answer 1

The correct option is B

Zinc

The explanation for correct options :

Option B, Zinc

• Galvanization is the process of applying a coating of zinc to iron to protect it from rusting.
• This protects iron from having direct contact with air and oxygen, preventing it from rusting.

The explanation for incorrect option:

Option A, Copper

• Copper is an element that undergoes oxidation easily, called corrosion.
• It is more reactive with air or oxygen than zinc.

Option C, Chromium

• Most stainless steel includes around 18 percent chromium.
• It hardens, toughens, and enhances corrosion resistance, particularly at high temperatures.

Option D, Nickel

• Its main application is alloying, especially with chromium as well as other metals to create stainless and heat-resistant steels.

Thus Option B, Zinc is the correct option.
