Question

What happens when an iron ball is put into sulphur

Answer 1

s, which says that Iron is more reactive than copper, therefore it can displace copper from its salts (here,copper sulphate).

The displacement reaction taking place can e written as :

Fe + CuSO4(aq) == FeSO4 + Cu

Iron + Copper Sulphate(aq) == Iron sulphate + copper

Now, enough basics, directly to question…

A fter 30 minutes:

1) The initial blue colour of copper sulphate solution is changed to light green colour of iron sulphate.

2) The initial silver colour of iron nail is changed to reddish-brown colour due to coating of copper metal on the nail.

Hope this will help you...... ✌
