Why wouldn't you put H2O(l) into the cell diagram the it is given on the cathode side?

In cell diagrams it is standard to leave out water but put H+

Hey! I think it's because H+ and the other ions contribute to charge difference and therefore, electron balance.
H2O doesn't really do much because it is neutral and doesn't contribute to electron balance and the oxidation number of either element doesn't change from one side of the reaction to another.
