Ammonia occurs in the atmospheres of the outer giant planets such as Jupiter (0.026% ammonia), Saturn (0.012% ammonia), and in the atmospheres and ices of Uranus and Neptune.

Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water.

- Ammonia solution

The reagent consists of a solution of silver nitrate, ammonia and some sodium hydroxide (to maintain a basic pH of the reagent solution).

- Tollens' reagent

Industrial ammonia is sold either as ammonia liquor (usually 28% ammonia in water) or as pressurized or refrigerated anhydrous liquid ammonia transported in tank cars or cylinders.

- Ammonia

Alternatively, aqueous ammonia can be added directly to silver nitrate solution.

- Tollens' reagent

Ammonia solution can dissolve silver oxide residues, such as that formed from Tollens' reagent.

- Ammonia solution

Diamminesilver(I) ([Ag(NH3)2]+) is the active species in Tollens' reagent.
