Question

what will happen
1) dilute H2 So4 is poured on a copper sulphate
2) Iron nails are placed in copper sulphate solution( balanced equation) I will mark you in brain list if you answer my question

Answer 1

CuSO4 + H2SO4 --> CuO3 + 2SO2 + H2O

Fe + CuSO4 --> FeSO4 + Cu

Answer 2

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.

THANKS…:D
