Cell Diagrams

[Kailani_Dial_2K]

Hi y'all I have a quick question, does the order of the elements in a cell diagram matter. I understand that the left hand side has to be the anode and therefore oxidation and the right side has to be the cathode and therefore reduction. I also know that the conducting solid has to be written on the outside of the diagram. However if I had the following problem (it's totally bs I'm making it up):

Pt(s) / Cl- (aq) / Cl2 (g) // K+ (aq) / K2 (g) // Pt(s)

Would it matter if I wrote it like this:

Pt(s) / Cl2 (g) / Cl- (aq) // K2 (g) / K+ (aq)// Pt(s)

Where the Cl2 and Cl- phases are switched?

Also if it does matter, why does it matter?

The too long to read version of this question is, does the positions within the separate halves of the cell diagram actually matter? And if they do can someone give me some guidelines on what to put where in the cell diagram with respect to the separate halves?

Hi! So I believe the order doesn’t matter as long as they're in the correct placement. Although I did remember that sapling required specific place,Mets. Either way the test will be multiple choice so it should have the placement already. Hope this helps!

Okay sweet I was thinking the same thing, but I just wanted to make sure. Thank you!!!

I was told that it is conventional to have the aqueous elements closest to the salt bridge. Can anyone confirm this?

I believe that order does matter (at least it does in Sapling #7 from last week). I think that the aqueous ions should be on the inner end:
Pt(s) / Cl2 (g) / Cl- (aq) // K+ (aq)/ K2 (g) / Pt(s)
Sapling specified that the ions that make contact with salt bridge should be placed in the middle.

The salt bridge ions that will be exchanged definitely should be touching the || since the notation is representing that in the cell the anion moves through the salt bridge or porous disc to balance the charge.

im pretty sure the order matters when you are ordering the phases (ie the aqueous phases will always be closest to the salt bridge bc they are coming into contact w it the soonest). however if they are in the same phase, i don't think the order matters

I was wondering this too, thank you guys for clearing that up.
