Question

Which of the following reaction(s) is/are possible? Give reason for your answer. i) Zn(s) + CuSO4(aq) ZnSO4(aq) + Cu(s) ii) Zn(s) + CaSO4(aq) ZnSO4(aq) + Ca(s

Answer 1

Hi

the first reaction is possible as Zn being a more reactive metal than Cu displaces it from its solution. which is called Displacement reaction.... whereas the second reaction is not possible as Calcium is more reactive than zinc.... no reaction would take place...

Hope it helps...
