Cell Diagram Question from Wednesday's (03/15/18) Lecture

Postby Anne 2L » Thu Mar 15, 2018 12:40 pm

What is wrong with this cell diagram?

Ag(s) I AgBr(s) II Br(aq) I Br2 (g)

I understand that the error we determined was that the left side of the cell diagram lacked a combatting electrode (Pt(s)). However, I remember someone asking about the line separating Ag(s) and AgBr(s) despite the fact that both are in the solid state. Dr. Lavelle mentioned that even though they are both solids it is still possible that they are in different states.

I'm confused as to whether separation in a cell diagram is dependent on the phase or the state of the molecules.

I think that for the purposes of this class, if two things are in the same state, we should separate them with a comma. So in this situation Ag(s) and AgBr(s) should be separated by a comma.

The line separates the electrode.
