Consider the equilibrium between ammonium hydroxide and ammonia and water:
+NH4 (aq) + -OH (aq) <=> NH3 (g) + H2O (l)
As you evaporate the water (or remove it by any other means in an attempt to isolate the ammonium hydroxide), the concentration of +NH4 and -OH go up, driving the equilibrium to the right, converting ammonium hydroxide to ammonia and water. The amount of water on the right side of the equation also goes down, but that only contributes to the shift in equilibrium when most of the water is already driven off.
Note: this equilibrium is somewhat simplified. Ammonium hydroxide is actually in equilibrium with aqueous ammonia which is, in turn, in equilibrium with ammonia gas.

aqueous ammonia and ammonium hydroxide are synonymous terms referring to a solution of ammonia in water. so once you separate the ammonia from water you would be left with a gas
so in shrot your answer is most definatly no
hope this helps

NO.
Ammonium hydroxide only exists in aqueous solution -- it is created by dissolving ammonia gas in water. When you evaporate the water, you drive off ammonia gas.

At room temperature, no.
At very low temperatures, yes.
You can crystalize *anything* if the temperature is low enough.

not without great difficulty. if you take away the water you're left with ammonia

No, and you can't smoke it either. You crazy fool.

Don't think so.
Why do you need to try to crystallise it anyway?
