Question

What would you observe on adding zinc granules to freshly prepared ferrous sulphate solution? Give reason for your answer.

Answer 1

Answer:

Explanation:

The zinc will replace the iron from the greenish ferrous sulphate

and forn white coloured zinc sulphate with iron.

Answer 2

Zn + FeSO4 → ZnSO4 + Fe

Explanation:

Zinc is more reactive than iron. So, when zinc granules are added to freshly prepared to iron (II) sulphate, a displacement reaction takes place. Zinc displaces iron and forms Zinc sulphate. So, the colour of solution fades from green to colourless. This is the property used in galvanizing, which is the process of applying a protective layer of zinc coating to protect steel or iron from corrosion.
