Explain the following chemical reactions and write the balanced chemical equations.
Zinc granules are added to copper sulphate solution

Explanation

Zinc which is more reactive than copper, removes copper from copper sulphate solution to form zinc sulphate. Blue colour of the solution fades due to displacement reaction.
`underset("Sulphate")underset("Copper")(CuSO_(4(sq)))+underset("Zinc")(Zn_((s)))rarrunderset("Zinc sulphate")(ZnSO_(4(aq)))+underset("Copper")(Cu_((s)))`
