This compound is used to turn aromatic amino acids yellow in the xanthoÂ·proteic test. A mixture of this compound and sulfuric acid adds a strong, three-atom, deactivating group to benzene which can then be reduced to aniline. When highly concentrated, this substance is referred to as "white fuming". This substance is produced industrially in a process that uses a platinum-rhodium catalyst and reacts oxygen with ammonia. This product of the Ostwald process is mixed in a one to three ratio with hydrochloric acid to make the gold dissolving aqua regia. For 10 points name this strong acid with formula HNO3 ["H-N-O-three"].
