Ammonia (English: Ammonia) is a colorless gas with a pungent odor. Weighing less than air, only about three-fifths
of air’s weight. It is a gas that contains one nitrogen and three hydrogens, so it is written as NH3 in its chemical
symbol. If ammonia is mixed with air, it is not life-threatening, but if it is inhaled in large quantities, it can be life-
threatening.
Ammonia is very soluble in water. When ammonia gas is dissolved in water, ammonia hydroxide, which has alkaline properties, is obtained. If the ammonia water is combined with hydrochloric acid, ammonia chloride is obtained. In fact, the name Ammonia was derived from Ammonia Chloride.
The name Ammonia is derived from the fact that Ammonia chloride was found near the temple of Jupiter Ammon in
Egypt. Ammonia was used in ancient times as an antler of a deer. Extracted from hooves and leather, it is called
“deer antler liquor”.
Ammonia as a pure gas was first produced in 1774 by an English chemist named Joseph Presley and named “alkaline
air”.
Ammonia combines less with other substances when it is dry and combines with other substances when it is dissolved in water.
Ammonia is obtained in large quantities as a by-product in the extraction of coking coal and coal gas from conventional coal. In order to extract coal gas, the blood of coal is put into a steaming pot such as a steam pot. When it is heated, ammonia water is also mixed as a by-product.
Also, ammonia can be obtained by directly combining hydrogen and nitrogen gas. In this method, after mixing one part of pure nitrogen gas and three parts of pure hydrogen gas, the temperature is heated to 500 to 700 degrees Celsius.
Ammonia becomes a liquid if cooled to 34 degrees Celsius. Ammonia boils at −33.34 °C and solidifies at −77.73 °C. When ammonia is cooled and pressed under good pressure, it can easily become a liquid, so it can be transported and transported in large steel barrels.
