WebJan 31, 2006 · HF and F2 are two completely different compounds. HF doesn't oxidize much of anything, but F2 certainly does. The reason why aqua regia is able to dissolve gold is because while the nitric acid portion of it oxidizes the gold, the chloride ion is able to move in and stabilize the gold ion and pull it out of solution by forming AuCl4(-). WebPotassium bromate (KBrO3), is a flour "improver" that strengthens dough and allows for greater oven spring and higher rising in the oven. Potassium bromate, commonly referred to as simply "bromate," is a slow-acting oxidizer, contributing its functionality throughout the mixing, fermentation and proofing stages, with important residual action ...

Gold(III) bromide is a dark-red to black crystalline solid. It has the empirical formula AuBr3, but exists primarily as a dimer with the molecular formula Au2Br6 in which two gold atoms are bridged by two bromine atoms. It is commonly referred to as gold(III) bromide, gold tribromide, and rarely but traditionally auric … See more The first mention of any research or study of the gold halides dates back to the early-to-mid-19th century, and there are three primary researchers associated with the extensive investigation of this particular area of chemistry: … See more The most common synthesis method of gold(III) bromide is heating gold and excess liquid bromine at 140 °C: 2 Au + 3 Br2 → Au2Br6 Alternatively, the … See more Catalytic chemistry Gold(III) bromide is used as a catalyst in a variety of reactions, but one of its most interesting uses is found in the Diels-Alder reaction.
