Ammonia water

Ammonia water, also known as aqueous ammonia, is a solution of ammonia (NH3) in water (H2O). It is a common commercial form of ammonia. It is a colorless liquid with a strong characteristic odor.

Chemical properties

Ammonia water is a weak base that reacts with acids to form salts and water. This reaction is exothermic, meaning it releases heat. The chemical equation for this reaction is:

NH3 + H2O → NH4+ + OH-

Ammonia water can also react with metals to form ammonium salts. For example, it reacts with aluminium to form aluminium hydroxide and ammonium hydroxide.

Uses

Ammonia water is used in a variety of applications. It is used in the manufacture of fertilizers, plastics, explosives, and dyes. It is also used in the textile industry for dyeing and printing. In the food industry, it is used as a leavening agent and a pH adjuster.

In the laboratory, ammonia water is used as a reagent in chemical reactions. It is also used in titrations to determine the concentration of acids.

Safety

Ammonia water is a corrosive substance and can cause burns to the skin and eyes. It is also harmful if inhaled or swallowed. Therefore, it should be handled with care and appropriate safety measures should be taken.
