Cell Diagrams

Postby Clara_Nguyen_1D » Wed Feb 08, 2017 3:41 pm

When drawing cell diagrams, what is the difference between using a straight line versus a comma? In the case of questions in which reduction and oxidation occur with the same element, which one goes on the reduction/oxidation cathode/anode side?

When drawing cell diagrams, I think the difference between using a line and comma is due to phase changes. If the element remains in the same phase (ex: aqueous to aqueous), you would use and comma. If the element undergoes a phase change (ex: aqueous to solid), you would use a line. Hope this helps!

To add onto what Diana said, a single line also represents that the two phases are in contact with each other, whereas the double lines represent the salt bridge!

Also to add on, anode, reaction losing electron, goes on the left side of the double bar, and cathode, the reaction gaining electrons, goes on the right side of the double bar.
