A systemic acidifying agent that has been used as a diuretic and an expectorant.

Inorganic salt, formula NH4Cl, formed from the neutralization of hydrochloric acid by ammonia. Ammonium chloride is a low vapor pressure solid, which deliquesces when the relative humidity exceeds 80%. It is thought to be present in the urban aerosol present in smog episodes. See deliquescence.

Colorless crystals which are soluble in water and ammonia. Dust is mildly irritating to eyes, nose and throat. See also Ammonia compounds, Quaternary ammonium chloride. Ammonium chloride is harmful to aquatic life in very low concentrations. Ammonia compounds (Includes ammonium chloride , ammonium hydroxide, benzalkonium chloride - Usually liquids with a pungent odor. Corrosive in concentrations found in commercial products (over 10%). Forms irritating cloramine gas when combined with chlorine-containing products. Fumes can cause irritation of the eyes, respiratory tract. Liquid can cause skin burns. Toxic to fish, and reduces oxygen in surface water. Uses: In many cleaning products, depending on concentration, as antiseptic, bactericide, fungicide, sanitizer, deodorant. Used in detergents as a surfactant. Also found in floor polish, glass window cleaners, household hard surface cleaners, rug and upholstery cleaners.

a white salt used in dry cells

Also known as ammonium muriate, sal ammoniac, salmiac. Colorless, odorless crystals or crystalline chunks; may also be a white, granular powder. Tendency to cake. Soluble in ethanol; near-insoluble in acetone or ether. Cooling, saline taste. Major industrial uses are in manufacture of dry cell batteries; dyes; fertilizers; washing powders; etc. Medical use as an expectorant. Normally packaged in barrels or multiwall paper or polyethylene sacks. In illicit heroin production, ammonium chloride can be used as a reagent to adjust alkalinity in the precipitation of morphine (as crude morphine base) from an opium solution.

Ammonium chloride or Sal Ammoniac (chemically ammonium chloride (NH4Cl); also nushadir salt, zalmiak, sal armagnac, sal armoniac, salmiakki, salmiak and salt armoniack) is, in its pure form, a clear white water-soluble crystalline salt with a biting, slightly sour taste. The aqueous ammonium chloride solution is mildly acidic.
