This substance comes in "white fuming" and "red fuming" varieties at 16 molar concentration.
This substance comes in "white fuming" and "red fuming" varieties at 16 molar concentration. It is commonly mixed with water at 68% concentration, at which it forms an azeotrope. Modern methods of producing pure forms of this strong oxidizing agent involve dehydrating the product with sulfuric acid and bubbling the reactant through hydrogen peroxide instead of water. Its large-scale production is done by mixing five equivalents of diatomic oxygen with four equivalents of (*) ammonia in the presence of a platinum/rhodium catalyst in the Ostwald process. Its pKa is approximately negative 1, and mixing it with hydrochloric acid gives aqua regia. For 10 points, name this compound with formula HNO3, a very strong acid.
