a) Zn + CuSO4 = ZnSO4 + Cu
In this reaction, zinc displaces copper from copper sulphate solution and forms zinc sulphate as zinc is more strongly reactive metal as compared to copper. The colour changes from blue to colourless as copper sulphate is blue coloured and zinc sulphate is colourless.
b)2Al + 6HCl = 2AlCl3 + 3H2
In this reaction, aluminum chloride and colourless hydrogen gas is formed.
c) No reaction takes place, as silver cannot displace copper from copper sulphate solution as silver is less reactive metal as compared to copper.
