I am confused on the order of the compounds in the Cell Diagram. I understand that the anode is on the left and the cathode is on the right, and I thought that the solid compounds normally go on the outside but I have seen solutions that say otherwise...can someone explain? Thanks. Also adding Platinum, that is just if the cathode doesn't have a solid correct?
Yes, the anode is on the left while the cathode is on the right. They are separated by the salt bridge, represented by the double bars (II). I believe the order doesn't matter; you just separate the species in terms of phase and separate them with commas if they are the same phase.
I'm confused on how the value of that works, not necessarily the writing of the cell diagram itself, but when you're allowed to have a negative Ecell value or not. I was told i just had to choose the cathode and anode based on whichever order I'd get a positive value, but on the hw and in the practice midterms I've seen a negative value, so if I got it wrong, I'd get writing the cell diagram incorrect as well.
