If you dont know the values then can you tell me the conductance of which solution should be higher?
Also can you tell me the conductances of ZnSo4 and CuSo4 for 0.5M, 0.01M, 0.1M?
Can you tell me the method to find the conductances?
Thank you very much

Altought water is itself a very poor conductor of electricity , the presence of ionic species in solution increases the conductance considerably.
The conductance of such electrolytic solution depends on the concentration of the ions and also on the nature of the ions present ( charges , mobility)
ZnSO4 >> Zn2+ + SO42-
CuSO4 >> Cu2+ + SO42-
Cu2+ ion is smaller then Zn2+ ion so it has a bigger mobility then Zn2+.
At the same concentration CuSO4 has a value of conductance bigger than ZnSO4.
When the concentration increases the conductance increases too

They dissociate completely, therefore high.
