On #23, it states: In the equilibrium constant expression for 2(NH4)2HPO4(s) + H2O(l) ---> 4NH4+(aq) + HPO4-(aq) + H2PO4-(aq) + OH-(aq),..... [H2O] is omitted because the salt is:
A. only weakly basic, and [H2O] is nearly constant
I chose this answer:
C. only weakly acidic, and [H2O] is nearly constant
So, how does one choose whether the water was acidic or basic in the reactants?
Thanks... I might post some more questions if I don't understand AAMC's explanations.
