I have read up on concentration cells and things like Nernst equations and standard potentials keep popping up. Like i said, i study civil engineering and have absolutely no background in electrochemistry.
This is where I am at so far..
In the copper sulphate solution i expect this to happen..
Fe
Fe
2+ + e
-and..
Cu
2+ + 2e
- Cu
Does do the Fe
2+ ions then join with the SO4
2- to form FeSO4?
Or does this also disassociate into Fe
2+ and SO4
2-And in the water I expect this to happen..
Fe
Fe
2+ + 2e
-Does H20 come into this somewhere? Complete madness!
Please correct me if I'm wrong..
But my understanding is that copper ions "wants" electrons, so takes the electrons from the iron (steel electrode).
I understand that for a potential difference to occur there has to be a movement of electrons from one electrode to the other. Not entirely sure where the demand is from..
