Question

What would you observe on adding Zinc granules to the Silver Nitrate solution? Give reason to your answer​

Answer 1

Answer:

Black coating is formed on zinc. Reason - zinc is more reactive than iron, therefore zinc displaces the iron from its solution.

Answer 2

Answer:

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.
