Question

iron fillings were added to a solution of copper sulphate.after 10 min it was observed that the blue colour of the solution has changed and a layer has deposited on iron filings .write colour that correspond to the colour of the solution and the colour of the coating respectively.also write the chemical equation

Answer 1

The color would turn green because iron from fillings displaces copper from the solution and copper gets deposited on iron fillings

fe+CuSo4=FeSo4+Cu

hope it helps

Answer 2

Colour of the solution turns from blue to green.

A reddis-brown coating of copper get deposited on the filings.

CuSO4+Fe=FeSO4+Cu
