One of the main sources of perchlorate contamination from natural nitrate fertilizer use was found to come from the fertilizer derived from Chilean caliche (calcium carbonate), because Chile has rich source of naturally occurring perchlorate anion. [74] Perchlorate concentration was the highest in Chilean nitrate, ranging from 3.3 to 3.98%. [51 ...
Sodium perchlorate is an inorganic compound with the chemical formula Na Cl O 4. It consists of sodium cations Na + and perchlorate anions ClO − 4. It is a white crystalline, hygroscopic solid that is highly soluble in water and ethanol. It is usually encountered as sodium perchlorate monohydrate NaClO 4 ·H 2 O.
These solids consist of the perchlorate anion linked via hydrogen bonds to H 2 O and H 3 O + centers. [9] An example is hydronium perchlorate. Perchloric acid forms an azeotrope with water, consisting of about 72.5% perchloric acid. This form of the acid is stable indefinitely and is commercially available. Such solutions are hygroscopic. Thus ...
The term can also refer to chemical compounds containing this anion, with chlorates being the salts of chloric acid. Other oxyanions of chlorine can be named "chlorate" followed by a Roman numeral in parentheses denoting the oxidation state of chlorine: e.g., the ClO − 4 ion commonly called perchlorate can also be called chlorate(VII).
Hydronium perchlorate is produced by the reaction of anhydrous perchloric acid and water in a 1:1 molar ratio: [2]. HClO 4 + H 2 O → [H 3 O] + ClO − 4. A more analytically reliable method was reported using the macrocyclic Schiff base of sodium 2,6-diformyl-4-methylphenolate and 2,6-diformyl-4-methylphenol as a chelating agent to sequester Cu(II): transmetallation of the macrocycle with ...
The preparation of perchlorate complexes can be challenging because perchlorate is a weakly coordinating anion. Chlorine trioxide is an important precursor to anhydrous perchlorate complexes. It serves as a source of ClO + 2 and ClO − 4.
Nitrosyl perchlorate is the inorganic compound with the formula NO(ClO 4).A hygroscopic white solid, it is the salt of the nitrosonium cation with the perchlorate anion. It is an oxidant and strong electrophile, but has fallen out of use with the availability of the closely related salt nitrosonium tetrafluoroborate NO(BF 4).
