The reduction of Cr(VI) by NH3OH+ has been studied in the pH range 0.0-4.7 and has been found to proceed by two equivalent steps following formation of an O-bonded chromate ester. The ester undergoes internal oxidation and reduction involving acid catalysis. A striking inductive effect due to protonation of H2N0Cr03_ is observed. Reactive,chromium intermediates include Cr(IV) which disproportionates and Cr(V) which is reduced by NH3OH+ to Cr(III). A reactive nitrogen intermediate, HNO, is oxidized primarily to HN02. NH3OH+ and (8) D. A.
