Cell Diagrams

Postby LNgo 1G » Tue Mar 03, 2020 11:43 am

Are ions that are not involved in the oxidation/reduction half reactions included in cell diagrams? For instance, if there is a cell containing AgNO3(aq), and Ag+ + e- -> Ag(s), would you include NO3-(aq) in the cell diagram ?

I don’t think spectator ions are included

Spectator ions are usually not included in cell diagrams because they don't really have an effect on the cell.

Why is it that in a lot of answers in 6L it would say "at the anode after reversal"? What does it mean for it to be reversed and does this change the potential?
