Question

Mg+Cuso4=MgSo4+Cu
Zn+Caso4= No reaction
Give reason. Why? ​

Answer 1

the concept used here is activity series of metals which is the arrangement of metals in decreasing order of activity on observing the series we find that magnesium is more reactive than copper so it is capable to displace copper from copper sulphate solution does forming magnesium sulphate solution now in case of zinc it is less reactive than calcium so it cannot displace Calcium from its sulphate solution and hands there is no reaction

Answer 2

because calcium is more reactive than zinc so displacement reaction is not taking place.
