Question

why do the copper & solution of copper sulphate change when we rake a solution of copper sulphate in breaker and put an iron nail in i​

Answer 1

Answer:

When an iron nail is immersed in the solution of copper sulphate then iron displaces 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
