Voltaic cell and potential differences!!!?
Which combination will give the highest voltage? and why? :(
Mg and Zn in CuSO4 , Mg and Fe in FeSO4, Zn and Fe in CuSO4 , Fe and Cu in CuSO4?
Does the solution affect anything?
Update:I forgot to ask. Which will give the LOWEST voltage too? :(

Look for the largest difference in Activity series/Electrochemical series.
That would be Mg/ Fe in FeSO4 giving highest potential.
Lowest by smallest difference namely Zn/Fe FeSO4 system
No at this level the solution will not affect much
