When reacting ammonia with an acid, why isn't water produced?

I have my chemistry exam tomorrow and I'm really confused, is adding ammonia to an acid not a neutralisation reaction?

I have the same exam too, I'm kind of nervous because I'm an A* student yet I properly bodged up my Biology exam.

When you add an Acid + Ammonia, you only get Ammonium ___ as the product. By this I mean:

HydroCHLORIC Acid + Ammonia = Ammonium CHLORIDE.

SULFURIC acid + Ammonia = Ammonium SULFATE.

NITRIC acid + Ammonia = Ammonium NITRATE.

It is not a neutralisation reaction as it isn't showing a reaction between an acid and a base. A base is a substance with a pH of greater than 7 and an Alkali is a base that dissolves in water.

Hope I helped you a bit :)

Ohhh ok, thanks so much, i was just confused though because in my revision guide it says that ammonia is an alkali and it makes a salt for a fertilser by adding it to an acid by neutralisation, but then when I did a past paper I got it wrong for adding water to the equation. :|

also i was just confused on how in the revision guide it says when you react ammonia and an acid e.g nitric acid uisng titration, to get the crystal you then have to evaporate the water - i don't know where this water comes from :S unless one of the acids/ alkali's have been diluted? :S
