Daniell Cell



So, I understand how it works, or I think I do. But some things are really bugging me, for some reason.

1. What would the cell stop working if you don’t add the salt bridge? I know that the anode side (zinc) would become more positively charged, but how does that affect the flow of electrons? Does the electron go somewhere else?
2. Is there any reason why on the zinc side ZnSO4 is used and on the copper side CuSO4 is used? Can I reverse the solution? I never understood why this specific cell using ZnSO4 and CuSO4, from a chemistry/education perspective, is so important. If it’s to introduce the concept of salt bridges, I understand, but if it’s to teach about oxidation, wouldn’t just a cell with H2SO4 work as well?

Thanks in advance!
