NH4Cl + NaOH? Please help

[From: ] [author: ] [Date: 11-11-07] [Hit: ]
NH3, and H2O will all be present.......
In an online assignment, I had to write the net reaction. I wrote:

NH4+(aq) + OH-(aq) --> NH3(g) + H2O(l)

It counted everything correct except the "gas" form of NH3. It says NH3 is not a gas in this reaction. Could someone please tell me why it isn't, and what the correct form should be?

Ammonia is fairly soluble in water, so the ammonia will actually form an aqueous solution. In fact, the formula NH4OH is often used to designate a concentrated solution of ammonia in water.

I'd argue that NH4+ (aq) + OH- (aq) -> NH3 (g) + H2O (l) is actually an equilibrium, not a reaction; in an aqueous solution of ammonia, NH4+, OH-, NH3, and H2O will all be present.
