Question

What happens when zinc is added to a solution of iron sulphate?

• A. Grey precipitate will be formed.
• B. Zinc will not displace iron from its solution.
• C. Green precipitate will be formed.
• D. Green solution is obtained; no precipitate is formed.

Answer 1

The correct option is A

Grey precipitate will be formed.

Zinc is more reactive than iron. Therefore, when zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.
