Ammonia in water is commonly known as Liquor Ammonia. It is safe to handle and helps to avoid the hazards accompanying Ammonia Gas by reducing the vapour pressure. It is an inorganic chemical/solvent with a wide range of applications in various chemical industries like Pharmaceuticals, rubber etc. It is a colourless liquid; in concentrated form, ammonium hydroxide can cause burns on contact with the skin; ordinary household ammonia, used as a cleanser, is dilute ammonium hydroxide.
The water solution is generally represented by the formula NH4OH; commercial grade ammonia solution has 25% Ammonia present.
