Question

What happens if we place an iron nail in the solid CuSO4 crystals?

Answer 1

Copper Sulphate Solution (CuSO4) is blue in colour. When iron nail is placed in it, we can observe the following:

1) reddish brown deposits on iron (these are of Copper)

2) colour of the solution turns from blue to light green.

The formula for this reaction is: Fe + CuSO4 --> FeSO4 + Cu

Here, Fe is more reactive than Cu. So Fe displaces Cu to form Iron Sulfate and Copper.

Hope it help you…….

Answer 2

Fe+CuSO4---------:FeSO4+Cu
