    I missed the lesson on it! :P Tried to look it up, but i'm a bit confused.

    I've been given half equations and the electrode potentials.
    How do I use these to draw out the cell diagrams?

    Thanks in advance everyone

    Yeah! Thanks, found it in second one..


    Lets see if I got this right then!
    Ag+ + e- -> Ag 0.80V
    Mg2+ + 2e- -> Mg -2.36
    Ag+ + Mg -> Mg2+ + Ag

    Mg | Mg2+ || Ag+ | Ag

    Cell E.M.F = 0.80 - (-2.36) = 3.16

    Is that right?

    I saw Pt(s) on some of the cell diagrams, what's that about?

    It's an inert platinum electrode, which is needed to act as a catalytic surface for some redox couples to react on.
