Detecting Ammonia | Gas Fact Sheet

Detecting Ammonia

Formula: NH3

CAS: 7664-41-7


Introduction: detecting ammonia. This is a compound comprised of nitrogen and hydrogen atoms, forming the chemical formula NH3. Its molecular structure resembles a trigonal pyramid, contributing to its distinctive characteristics. In this article, we discuss its properties and applications, and provide our recommendation for best detecting practices.

Physical Properties: Ammonia exists as a colourless gas under standard conditions. It is recognisable by its sharp, pungent odour, detectable even at low concentrations of 5 ppm. Ammonia is also highly soluble in water, resulting in the formation of an alkaline solution known as ammonium hydroxide.

Chemical Properties: Exhibiting versatile properties, ammonia acts as a base, readily accepting protons to form ammonium ions (NH4+). It serves as a nucleophile in organic reactions and forms coordination complexes with metal ions.

Industrial Applications: Ammonia is primarily utilised in fertiliser production as a crucial nitrogen source for plant growth. It is also a key precursor in the synthesis of various chemicals, including nitric acid, urea, and ammonium salts.

Environmental Impact: While essential in agriculture and industry, ammonia release can lead to adverse environmental effects. Farm runoff causes water pollution and eutrophication. Industrial emissions can lead to air pollution and acid rain.

Safety Considerations: Handling ammonia requires caution due to its toxic and corrosive nature. Inhalation of high concentrations can cause respiratory irritation, while contact with liquid ammonia can result in severe frostbite. Proper safety measures, including ventilation and protective equipment, are crucial when working with ammonia.
