Chemical and Physical Properties
Ammonium hydroxide is a solution of ammonia in water. It is also known as ammoniacal water, aqueous ammonia or ammonia in solution. Ammonia deprotonates water to give NH4+ and OH- which is why is more commonly expressed as NH3(aq). You can see this reaction below:NH3 + H2O ⇋ NH4+ + OH−At 15°C, the density of a saturated ammonia solution is 0.88g/mol. This contains 35% ammonia (by mass), a molarity of approximately 18 mol/L and 308 grams of ammonia per litre of solution (g/L w/v). Interestingly, at higher temperatures its density decreases and molarity increases.Therefore, if saturated solutions are prepared at cold temperatures, the ammonia concentration will drop as soon as the solution is warmed. Excess will then be released as ammonia gas. In extreme cases, unsealing a container with ammonia could burst or rupture if stored in warm conditions.
