Cell Diagram

[Amanda_Ye_1G]

I'm having trouble writing cell diagrams. Is there a special format we need to write them in? Does the order matter when you use a comma versus a "|"?

[shannon_tseng_3L]

the format should be
anode metal | anode ion || cathode ion | cathode metal (or Pt)

[Arshia_Sabir_3E]

The first thing to know is that a double vertical line (||) is used to separate the anode half reaction from the cathode half reaction (represents salt bridge).
A single vertical line (|) is used to separate solid, liquid, gas, or aq on the same side.
A comma is used to separate same states of matter on the same side.
so for instance, if you have two aqueous solution on the anode side you'll separate them with a comma and you have one gas and aqueous you'll separate them with a vertical line.

I hope this helps!

Does the order matter when you separate molecules of the same state with commas. Do we usually range them in the order of charges? and when we separate gas from aqueous with a solid verticle line, is there a order in which we have to put them in?

[Brenton Hwee 2J]

No, the order does not matter when they are separated by a comma. However, for the solids they are usually placed at the end of the cell diagram, and gases usually go right before the electrode, separated by a line.

Is it possible that we will get marked down if we put it out of order when they are separated by the single vertical line? For example, if we put the solids at the end (correctly) but put the rest out of order (such as those that are gas, liquid, or aq)?

[Jocelyn Sandoval 3B]

I think that there is a specific order in which you should have them inside of the diagram. The aqueous solution should be closest to the salt bridge, which is represented by "II". Then, I believe that the liquid goes after that and then its gas. Solids are the last ones.

Correct

I don't deduct points for this.

Correct. But we won't deduct points if you put solids at the end (correctly) but put the rest out of order (such as those that are gas, liquid, or aq).

[YuniLee_1K]

In some of the homework answers in the solution manual, the cell diagram is depicted as "solid | solid | soln || soln | solid", essentially with more than one solid on one side of the set-up. When does this sort of electrochemistry set-up occur, and why is there a line rather than a comma separating the two solids?

[Hue_Vo_1D]

The format should be that:
The anode always goes on the left and cathode on the right. Separate changes in phase by | and indicate the the salt bridge with ||.

Other important notes:
Add "Pt(s)"-Platinum, which an inert conductor that must be in the cell with the half reaction that has only gas and aqueous phases.
Separate the same phase substances with comma.
