Use：: Selenium dioxide is reduced to selenium metal when heated with carbon and other reducing agents. When heated with ammonia, selenium dioxide forms selenium, nitrogen and water: 3SeO2 + NH3 3Se + 2N2 + 6H2O Ammonia reacts with selenium dissolved in ethanol to form ammonium ethyl selenite, NH4(C2H5)SeO3. Reaction with nitric acid forms selenic acid: Se + 2HNO3 H2SeO4 + 2NO Selenium dioxide is reduced by hydrazine to black amorphous selenium: SeO2 + N2H4 Se + N2 + 2H2O Hydroxylamine hydrochloride reduces selenium dioxide to reddish-brown amorphous selenium: SeO2 + 4NH2OHHCl Se + 2N2 + 6H2O + 4HCl The dioxide rapidly absorbs hydrogen halides, forming selenium oxyhalides: SeO2 + HBr SeOBr2 + H2O Reaction with thionyl chloride yields selenium oxychloride: SeO2 + SOCl2 SeOCl2 + SO2
