Perchloric acid is a mineral acid with the formula H Cl O 4. It is an oxoacid of chlorine . Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid , nitric acid and hydrochloric acid .
A perchlorate is a chemical compound containing the perchlorate ion, ClO − 4, the conjugate base of perchloric acid (ionic perchlorate).As counterions, there can be metal cations, quaternary ammonium cations or other ions, for example, nitronium cation (NO + 2).
Perchloric acid rubidium salt, Rubidium chlorate(VII), Rubidii perchloras (lat.) ... Chemical formula. RbClO 4 Molar mass: 184.918 g/mol Appearance Colorless crystals
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 ...
Cobalt(II) perchlorate hexahydrate is produced by reacting cobalt metal or cobalt(II) carbonate with perchloric acid, followed by the evaporation of the solution: [1] CoCO 3 + 2 HClO 4 → Co(ClO 4) 2 + H 2 O + CO 2. The anhydrous form cannot be produced from the hexahydrate by heating, as it instead decomposes to cobalt(II,III) oxide at 170 °C.
Being the conjugate base of the strongly acidic perchloric acid, perchlorate is very weakly basic. It is more commonly encountered as a counterion in coordination chemistry. Illustrative of its low basicity is the ability of water to outcompete perchlorate as a ligand for metal ions is indicated by the multitude of aquo complexes with ...
Silver perchlorate is the chemical compound with the formula AgClO 4. This white solid forms a monohydrate and is mildly deliquescent. It is a useful source of the Ag + ion, although the presence of perchlorate presents risks. It is used as a catalyst in organic chemistry.
One synthesis uses fluorine and perchloric acid, [4] though the action of ClF 5 on water is another method. [citation needed] F 2 + HClO 4 → FClO 4 + HF. Another method of synthesis involves the thermal decomposition of tetrafluoroammonium perchlorate, NF 4 ClO 4, which yields very pure FClO 4 that may be manipulated and frozen without ...
