Question

Take a small quantity of copper sulphate crystals and dissolve it in a small quantity of water to obtain blue coloured solution. Add a few drops of dilute sulphuric acid. Now, put 3-5 medium sized iron nails in it. Soon the colour of blue solution changes to green and a brown deposit appears on the iron nails. Change of colour from blue to green in the above activity represents:​

Answer 1

Answer:

Change in the colour of the solution represents displacement reaction.

Explaination:

In displacement reaction, a high reactive metal displaces a less reactive metal in it's salt solution.

Here too, the copper from the copper sulphate got displaced by iron

The equation of this reaction is

CuSO4 + Fe = FeSO4 + Cu
