Question

4. Why do the colour & solution of copper sulphate change when we take a solution of
copper sulphate in a beaker and put an iron nail in it?
​

Answer 1

Answer:

The colour and solution of copper sulphate change when we take a solution of copper sulphate in a beaker and put iron nail in it because iron is more reactive than copper so it displace copper from copper sulphate and forms iron sulphate. The chemical equation can be written as: Fe+CuSO4→Cu+FeSO4.
