What do you think happens?


The ammonia comes out of a solution as a gas. When you buy concentrated ammonia solution (approx. #15*mol*L^-1#) in water and you get a whiff of this solution, the pungent odour of ammonia (gas) will bring tears to your eyes. Of course, I do not recommend that you try this. Many cleaning products are ammonia based, and you can smell the distinctive odour.

The degree of acid base dissociation with respect to ammonia in aqueous solution is fairly minimal.

#NH_3(aq) + H_2O(l) rightleftharpoons NH_4^+ + HO^-#

#K_(eq)# #=# #1.8xx10^-5" at 298K"#
