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 ...
Before the 1990s, tetrafluoroborate, hexafluorophosphate, and perchlorate were considered weakly coordinating anions. Only by exclusion of conventional solvents were transition metal perchlorate complexes found to exist, for example.
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).
Perchlorates are chemical compounds containing the chlorate(VII) anion (ClO 4 −). Pages in category "Perchlorates" The following 53 pages are in this category, out of 53 total.
Hydronium perchlorate is an inorganic chemical compound with the chemical formula [H 3 O]ClO 4. It is an unusual salt due to it being a solid and stable hydronium salt. It consists of hydronium cations [H 3 O] + and perchlorate anions ClO − 4 .
The anhydrous solid is rarely encountered but several hydrates are known. Most important is the perchlorate salt of the aquo complex copper(II) perchlorate hexahydrate, [Cu(H 2 O) 6] 2+. [3] Infrared spectroscopic studies of anhydrous copper(II) perchlorate provided some of the first evidence for the binding of perchlorate anion to a metal ion. [4]
