When we add ;
1)zinc to copper sulphate solution the reaction is
Zn+CuSO4 to form ZnSO4+Cu
At first the colour of CuSo4 is blue but on adding Zn it's colour fades due to formation of ZnSO4...
2)On adding lead to cupric chloride solution the reaction is
Pb+CuCl2 to form PbCl2 + Cu
as a result of formation of lead chloride the blue colour fades to colourless...
hope it's correct

amanchy123: According to ur answer you want to say both reaction will give colourless
avantika12gmailcom: i m not sure
amanchy123: Ok

In first case blue colour will change to colourless due to formation of ZnCl and in second case blue colour will change to white due to formation of PbCl2
