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). The term perchlorate can also describe perchlorate esters or covalent ...
The distribution of perchlorate tablets, or the addition of perchlorate to the water supply, would need to continue for 80–90 days (~10 half-life of 8.02 days) after the release of iodine-131. After this time, the radioactive iodine-131 would have decayed to less than 1/1000 of its initial activity at which time the danger from the biological ...
Sodium perchlorate is the precursor to ammonium, potassium and lithium perchlorate salts, often taking advantage of their low solubility in water relative to NaClO 4 (209 g/(100 mL) at 25 °C). [6] It is used for denaturating proteins in biochemistry and in standard DNA extraction and hybridization reactions in molecular biology.
Ammonium perchlorate ("AP") is an inorganic compound with the formula NH 4 ClO 4.It is a colorless or white solid that is soluble in water. It is a powerful oxidizer.Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant.
From a microbial standpoint, the presence of natural chlorate could also explain why there is a variety of microorganisms capable of reducing chlorate to chloride. Further, the evolution of chlorate reduction may be an ancient phenomenon as all perchlorate reducing bacteria described to date also utilize chlorate as a terminal electron acceptor ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Sodium chlorate – much less stable than perchlorate, hazardous, also serves as yellow colorant, hygroscopic Nitrates (when mixing with aluminium, boric acid should be added as a stabilizer): Potassium nitrate – very common, used in black powder and wide variety of compositions.
A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...
