Though tin occurs lower than iron in the electrochemical series, yet it is coated on steel for corrosion protection, because of its________________?
Correct answer: A. Resistance to vegetable acids as the tin plate are commercially used in 'canning' industry
- A. Resistance to vegetable acids as the tin plate are commercially used in 'canning' industry
- B. Abundant availability
- C. Lower cost
- D. None of these
Explanation
Tin is used on steel cans because it resists attack by vegetable acids and food materials, making it suitable for the canning industry. Its position in the electrochemical series is not the main reason for this application.
