Ammonia is a chemical compound with three hydrogen atoms and a nitrogen atom. Ammonia is in the standard state of the gas. Ammonia in the form of ammonia salt was first recognized by Iranian Muslim chemists Jaber ibn Hayan in the 8th century. One of the important uses of ammonia is the production of chemical fertilizers.

Ammonia is the most important hydrogen-nitrogen compound and is naturally occurring in organic matter decomposition. Ammonia is a colorless gas, with an incredibly nasty tasting that is tearful and choking. Ammonia gas is lighter than air and easily converted to liquid. Ammonia is highly soluble in a froth at 77.7 degrees Celsius and boils at a minus 33.3 degrees Celsius. The specific gravity of the ammonia saturation solution is 88 grams per cubic centimeter. Ammonia gas is flammable and its flammability range is 16-25% vol. Of ammonia gas in the air. The presence of petroleum and other pollutants increases the risk of fire. Proximity and contact with ammonia with silver and mercury generate foreman of silver and mercury that are highly explosive. Ammonia gas decomposes in the heat from 400 degrees to hydrogen and produces hydrogen. The spatial shape of ammonia is pyramidal and the bonding angle between the two hydrogen atoms in ammonia is 107.8 degrees. The ancient Romans used ammonium chloride as money and deposits. They collected ammonium stones from a place called Jupiter's Temple, the new Libya. Ammonia in the form of ammonia salt was first discovered by the Iranian chemist Jaber ibn Hayan in the 8th century. In the 15th century, Basilius Valentinus showed that ammonia can be obtained from alkali action on ammonia salts.
