Water and Cell Diagrams

Postby Lily Guo 1D » Sat Mar 17, 2018 8:57 pm

Would you ever include H2O in a cell diagram if it were part of a half reaction? For example, how would you write this reduction half reaction in a cell diagram: NO3- + 2H + e - ==> NO2 + H2O?

no,If something is aqueous it is implied that there is water

I may be wrong, but I think water is not usually included in a cell diagram, since water and hydrogen tend to not be oxidized or reduced (especially as water molecules or H+ ions). Also, cell diagrams note both the anode and the cathode, as opposed to just one side of the reaction (ie, one half reaction).

Water is assumed because of the aqueous states.
