Nitrate chlorides are mixed anion compounds that contain both nitrate (NO 3 −) and chloride (Cl −) ions. Various compounds are known, including amino acid salts, [ 1 ] and also complexes from iron group , rare-earth , and actinide metals.

A chloride ion is a structural component of some proteins; for example, it is present in the amylase enzyme. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. [19]
Chlorine nitrate, with chemical formula ClONO 2 is an important atmospheric gas present in the stratosphere. It is an important sink of reactive chlorine and nitrogen, and thus its formation and destruction play an important role in the depletion of ozone.
An example of back titration, the Volhard method, named after Jacob Volhard, involves the addition of excess silver nitrate to the analyte; the silver chloride is filtered, and the remaining silver nitrate is titrated against ammonium thiocyanate, [1] with ferric ammonium sulfate as an indicator which forms blood-red [Fe(OH 2) 5 (SCN)] 2+ at the end point:
Potassium nitrate can be made by combining ammonium nitrate and potassium hydroxide. NH 4 NO 3 + KOH → NH 3 + KNO 3 + H 2 O. An alternative way of producing potassium nitrate without a by-product of ammonia is to combine ammonium nitrate, found in instant ice packs, [30] and potassium chloride, easily obtained as a sodium-free salt substitute.
Nitrosyl chloride is the chemical compound with the formula NOCl. It is a yellow gas that is commonly encountered as a component of aqua regia , a mixture of 3 parts concentrated hydrochloric acid and 1 part of concentrated nitric acid .
Europium chloride, nitrate and oxide have been tested for toxicity: europium chloride shows an acute intraperitoneal LD 50 toxicity of 550 mg/kg and the acute oral LD 50 toxicity is 5000 mg/kg. Europium nitrate shows a slightly higher intraperitoneal LD 50 toxicity of 320 mg/kg, while the oral toxicity is above 5000 mg/kg.
