Question

What happens when a piece of copper metal is placed in iron sulphate solution?

• A. Copper will not displace iron from its solution.
• B. Grey precipitate of iron is formed.
• C. Deep blue colour solution of iron sulphate changes to green solution of copper sulphate.
• D. Green colour solution of iron sulphate changes to blue solution of copper sulphate.

Answer 1

The correct option is A

Copper will not displace iron from its solution.

When a piece of copper is placed in iron sulphate solution then no change will be observed. This is because copper is less reactive than iron, therefore, unable to displace it from its solution.
