Question

why does the colour & solution of copper sulphate change when we take a solution of copper sulphate in a breaker and put an iron nail in it?​

Answer 1

Answer:

when we put a iron nail in the solution of copper sulphate iron is a much more reactive metal than copper so it will displace copper from its salt solution very easily and will form iron sulphate and copper was left the colour of copper sulphate was blue and the new solution formed was of iron sulphate and the colour of the new solution formed i.e. iron sulphate is green

Explanation:

cuso4+Fe it will form Feso4 +cu

Answer 2

Answer:

When an iron nail is immresed in the solution of copper sulphate than iron displays copper from the solution of copper sulphate because iron is more reactive than copper therefore copper sulphate solution colour changes from blue to pale green.
