Ammonium chloride NH4Cl (also Sal ammoniac, salmiac, nushadir salt, sal armagnac, sal armoniac, salt armoniack) is, in its pure form, a clear white water-soluble crystalline salt of ammonia. The aqueous ammonium chloride solution is mildly acidic. Sal ammoniac is a name of natural, mineralogical form of ammonium chloride. The mineral is especially common on burning coal dumps (formed by condensation of coal-derived gases), but also on some volcanoes.

 

SOURCES

 

The substance occurs naturally in volcanic regions, forming on volcanic rocks near fume-releasing vents. It is a by-product of the Solvay process used to produce sodium carbonate.[2]

 

Ammonium chloride is prepared commercially by reacting ammonia (NH3) with hydrogen chloride (HCl). As these chemicals are corrosive, this process has to be performed in vessels lined with nonreactive materials (e.g. glass, enamel, lead, or PVC).[2]

 

NH3 + HCl → NH4Cl

 

This reaction can occur if poorly sealed bottles of household ammonia (ammonium hydroxide) and hydrochloric acid are stored in close proximity, leading to crystals forming around the openings of the bottles (mostly appear on those leaking more slowly).

 

REACTIONS

 

Ammonium chloride appears to sublime but this process actually involves decomposition into ammonia and hydrogen chloride gas.[2]

 

NH4Cl → NH3 + HCl

 

Ammonium chloride may be reacted with a hydroxide base, e.g. sodium hydroxide, to release ammonia gas:  NH4Cl + NaOH → NH3 + NaCl + H2O

 

If test tubes of ammonia solution and hydrochloric acid are brought close together, a smoke composed of microcrystal’s of ammonium chloride will slowly rise out of the tube.

 

APPLICATIONS

Ammonium chloride crystal(s).

 

CHEMISTRY AND PHYSICS

 

Ammonium chloride dissolved in water becomes an acid. Ammonium chloride is used to produce low temperatures in cooling baths. For example, the zero point of Fahrenheit temperature scale is determined by placing the thermometer in a mixture of ice, water, and ammonium chloride. Ammonium chloride solutions with ammonia are used as buffer solutions.

 

BIOLOGY AND AGRICULTURE

 

In biological applications ammonium chloride acts as a nitrogen source and is used in fertilizers, as a feed supplement for cattle and as an ingredient in nutritive media for yeast microbiological organisms.

 

PYROTECHNICS

 

Ammonium chloride is an ingredient in fireworks and safety and contact explosives.

 

TEXTILE AND LEATHER

 

Ammonium chloride is used in the textile and leather industry in dyeing, tanning textile printing and to luster cotton.

 

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 work pieces by reacting with the metal oxides at the surface to form a volatile metal chloride. 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.

 

FOOD

 

In several countries ammonium chloride is known as sal ammoniac and used as food additive. The E number for ammonium chloride used as a food additive is E510.

Sal ammoniac is used to spice up dark sweets called salty liquorice and in the flavouring Salmiakki Koskenkorva for vodkas. Sal ammoniac is also used in baking to give cookies a very crisp texture.
