Aqua Ammonia

Aqua Ammonia is also known as ammonia solution, ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqueous ammonia, or simply ammonia.

TCC’s Aqua Ammonia is a clear, colorless liquid with a strong pungent ammonia odor. It is a solution of ammonia gas (a compound of nitrogen and hydrogen) in water.

Household strength aqua ammonia is primarily used with other ingredients as a cleansing agent, although ammonia is also sold as a cleansing agent by itself. It is sold plain, as lemon-scented (and typically colored yellow) or pine-scented (green). It is used in industry as a precursor to some alkyl amines. It is also used in furniture making, as a food additive, and in laboratories in qualitative inorganic analysis.


TCC’s Aqua Ammonia is a widely used ingredient in numerous cleaning agents, including many window-cleaning formulas. However, aqua ammonia is also sold as a cleaning agent by itself, usually labeled as simply “ammonia.” It is sold plain, lemon-scented (and typically colored yellow), or pine-scented (green).

In industry, aqua ammonia is used as a precursor to some alkyl amines. Hexamethylenetetramine forms readily from aqua ammonia and formaldehyde. Ethylenediamine forms from 1,2-dichloroethane and aqua ammonia.

In furniture making, aqua ammonia is traditionally used to darken or stain wood containing tannic acid.

As a food additive, aqua ammonia is used as an antimicrobial. Grocery stores particularly use aqua ammonia to make beef safe.

In laboratories, aqua ammonia is used in traditional qualitative inorganic analysis. When it is mixed with dilute hydrogen peroxide in the presence of a metal ion, such as Cu2 , the peroxide will undergo rapid decomposition.

Aqua Ammonia, aqueous ammonia and ammonium hydroxide are synonymous terms referring to a solution of ammonia in water. Aqua ammonia is a clear, colorless liquid with a strong pungent ammonia odor.

Aqua ammonia is classified as a weak base. It ionizes much less completely in water than does a strong base such as sodium hydroxide.

Aqua ammonia is corrosive to copper, copper alloys, aluminum alloys and galvanized surfaces. The base solution is an excellent acid neutralizer. Its pH varies with concentration.
