Question

Paheli appeared a blue coloured solution of copper sulphate in beaker a and placed an iron nail in it

Answer 1

Answer:

The solution will turn green and copper deposit will form on nail

Explanation:

If an iron nail is dropped in copper sulphate solution, the iron will displace copper since iron is more reactive than copper. Iron sulphate solution will be formed and brown deposits of copper will form on iron nail. It is an example of displacement reaction.

Copper sulphate (blue) + iron nail => Iron sulphate (green) + Copper deposit (brown)

CuSO4 + Fe => FeSO4 + Cu
