Question

Statement I: In electroplating, a superior metal is coated with an inferior metal.
Statement II: When iron is coated with zinc metal, iron becomes more resistant to corrosion.

• A. Statement I is true and statement II is false.
• B. Statement I is false and statement II is true.
• C. Both the statements are true.​
• D. Both the statements are false.​

Answer 1

The correct option is B Statement I is false and statement II is true.

Electroplating is a process in which one metal is coated with another material. In electroplating, an inferior metal (affected by atmospheric humidity, carbon dioxide, etc.) is coated with a superior metal (not affected by humidity or carbon dioxide).

Electroplating is widely used for coating metal objects with a thin layer of different metals. When iron is coated with zinc metal, iron becomes more resistant to corrosion. So, zinc coated iron is used for bridges and in automobiles.
Therefore, statement I is false and statement II is true.
