Question

Can zinc displace iron from iron sulphate solution?

Give its word equation and reason also.​

Answer 1

Explanation:

Answer: (a) No reaction will take place because copper is very less reactive. (b) Iron being more reactive than copper will replace copper from its solution and brown coating of copper is deposited on the iron nails.

Answer 2

Answer:

When zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, therefore, it displaces iron from its solution of iron sulphate and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.
