Applications:

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 workpieces 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. 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

Ammonium Chloride is also used as a diuretic in forced acid diuresis.

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.

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, in cleaning products.
