When dealing with two compounds that are in different phases, how do you know which to list first in the cell diagram? For instance, if the two compounds on the reduction side of my diagram are Cl2(g) and Cl-, which do I put first?

There is no convention for which compound to put first, but it would make logical sense to place Cl2(g) before Cl-(aq) to show that Cl2 is being reduced to Cl-.

chem mod posted in another post that electrodes and solids are furthest from the salt bridge, followed by liquids, gases, and aqueous solutions, but most people usually order it reactants to products

From what I have seen the aqueous compounds are written closest to the middle, the closest to the salt bridge and then the solids are farthest compounds from the salt bridge. Liquids and gases are then written in between.

I prefer to go in the order of what is happening. So with oxidation I start off with some kind of solid and then move to the positive ion. With reduction I start with the positive ion and then move to the solid.
