order of a cell diagram

Postby Michelle Nwufo 2G » Tue Mar 12, 2019 4:35 pm

Can someone please reiterate the order of a cell diagram and where H+ goes?

the electrode goes on the outside while the anode is to the left and the cathode is to the right of the double lines (||), indicating a salt bridge. Species that are in the same phase are separated by a comma, while everything else is separated by a single line (|). I'm not sure what you mean by h+.

The order of a cell diagram would have a structure of:
anode|gas, liquid| aq. molecule || aq. molecule|gas, liquid|cathode.

Everything to the left of the || is the oxidation reaction while everything to the right of the || is the reduction reaction.

H+ if it is in aqueous state would be in the section where "aq. molecule" is labeled.

Thank you! And if there are coefficients in the half reactions, do we include them in the cell diagram?

If there are coefficients in the half reactions, you do not need to include them. Just remember to separate the phases with a bar and the two half reactions with a double bar.
