Applications
Ammonium chloride crystal(s)
The main application of ammonium chloride is as a nitrogen source in fertilizers (corresponding to
90% of the world production of ammonium chloride), e.g. chloroammonium phosphate. The main
crops are rice and wheat in Asia.
Ammonium chloride was used in pyrotechnics in the 18th century but was superseded by safer and
less hygroscopic chemicals. Its purpose was to provide a chlorine donor to enhance the green and
blue colours from copper ions in the flame.
It had a secondary use to provide white smoke but its ready double decomposition reaction with
potassium chlorate producing the highly unstable ammonium chlorate made its use very suspect.
Metalwork
Ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized or soldered.
It works as a flux by cleaning the surface of workpieces by reacting with the metal oxides at the
surface to form a volatile metal chloride. For this purpose, it is sold in blocks at hardware stores for
use in cleaning the tip of a soldering iron and can also be included in solder as flux.
Medicine
Ammonium chloride is used as an expectorant in cough medicine. Its expectorant action is caused
by irritative action on the bronchial mucosa. This causes the production of excess respiratory tract
fluid which presumably is easier to cough up. Ammonium salts are an irritant to the gastric mucosa
and may induce nausea and vomiting.
Ammonium chloride is used as a systemic acidifying agent in treatment of severe metabolic
alkalosis, in oral acid loading test to diagnose distal renal tubular acidosis, to maintain the urine
at an acid pH in the treatment of some urinary-tract disorders.
Food
In several countries, ammonium chloride, known as sal ammoniac, is used as food additive under
the E number E510, commonly as a yeast nutrient in breadmaking. It is a feed supplement for cattle
and an ingredient in nutritive media for yeasts and many microorganisms.
Ammonium chloride is used to spice up dark sweets called salty liquorice (very popular in Nordic
countries, especially in Finland), in baking to give cookies a very crisp texture, and in the vodka
Salmiakki Koskenkorva for flavouring. In India and Pakistan, it is called "Noshader" and is used to
improve the crispness of snacks such as samosas and jalebi.
In the laboratory
Ammonium chloride is used to produce low temperatures in cooling baths.Ammonium chloride
solutions with ammonia are used as buffer solutions.
In paleontology, ammonium chloride vapor is deposited on fossils, where the substance forms a
brilliant white, easily removed and fairly harmless and inert layer of tiny crystals. This covers up
any coloration the fossil may have, and if lighted at an angle highly enhances contrast in
photographic documentation of three dimensional specimens.The same technique is applied in archaeology to eliminate reflection on
glass and similar specimens for photography.
Flotation
Giant squid and some other large squid species maintain neutral buoyancy in seawater through an
ammonium chloride solution which is found throughout their bodies and is lighter than seawater.[citation needed] This differs from the method of flotation used by most fish, which involves a
gasfilled swim bladder. The solution tastes somewhat like salmiakki and makes giant squid
unattractive for general human consumption.
Other applications
Ammonium chloride is used in a ~5% aqueous solution to work on oil wells with clay swelling
problems. It is also used as electrolyte in zinc–carbon batteries. Other uses include in hair shampoo, in the glue that bonds plywood, and in
cleaning products. In hair shampoo, it is used as a thickening agent in ammonium-based surfactant systems, such as ammonium lauryl sulfate. Ammonium chloride is used in the
textile and leather industry in dyeing, tanning, textile printing and to luster cotton.
