I used aqueous, because if it is in a solution, and dissolved gas in a solution then it must be aqueous. However, if there is gas around the electrodes, it can reduce too. AFAIK, as both can occur, both are correct.
Was that titration the one that ended up being 0.050001 molar or something? I think I remember it being really round too.
