Well, since they are ALL aqueous solutions, their ion product, #[HO^-][H_3O^+]# #=# #10^(-14)# under standard conditions.

Explanation:

And taking negative #-log_10# of both sides, we would find that,

#pOH+pH=14#.

For water #pOH=pH=7#. For vinegar, a weak acid, #pH~=2.2#. For ammonia, a weak base, #pH~=11.5#.

What are #pOH# for vinegar, and ammonia?
