like with those home ice cream makers (where you crank it by hand... etc) How much colder does the salt make the ice? Does it lower the temp by only a few degrees or is it a decent amount like 10 or more degrees difference?

I hope I worded this so you all can understand what I am trying to say......

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
