Question

Colour of copper sulphate solution changes when zinc strip is dipped in it.give reason​

Answer 1

Answer:

When zinc is added to copper sulphate solution, then the zinc metal displaces copper from copper sulphate to form zinc sulphate. This happens because zinc is more reactive than copper. CuSO4 solution has a blue colour while ZnSO4 solution is colourless. Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq).
