Bromine, reaction with hydrogen nitric oxide

Reacts violently with strong oxidizers, ammonium persulfate, bromine dioxide, nitric acid, perchlorates, permanganates, peroxides, sulfuric acid. Exothermic reaction with hydrogen chloride. Incompatible with lead dioxide, magnesium. Due to low electric conductivity, this substance may generate electrostatic charges as a result of agitation and flow. 

Bodenstein has, however, shown that the combination of nitric oxide and oxygen 2N0 + 02 = 2N02 is a homogeneous change which is kinetically of the third order, and the same appears to apply to the combination of nitric oxide with chlorine and with bromine f and to the reaction between nitric oxide and hydrogen. J 2NO + C12 = 2NOC1 2NO + Br2 = 2NOBr 2NO + H2 = N20+H20... 

Aldoses can be degraded by the following two reactions. First the aldehyde is oxidized with bromine water to form a carboxylic acid. Next the carboxylic acid is decarboxy-lated with hydrogen peroxide and ferric sulfate leaving an aldehyde. The new aldose is one carbon shorter. When glucose is degraded in this manner, and the product is oxidized by dilute nitric acid, an optically active compound is formed. 

WO2 dissolves in warm, concenhated mineral acids and in boiling, concentrated alkali hydroxide solutions. It dissolves rapidly in diluted and cone. H2O2. Nitric acid oxidizes it to WO3. About the behavior with respect to hydrogen, see Chapter 3. Higher oxides are formed with oxygen at elevated temperature. Reaction with chlorine leads to the formation of WOCI4 and WO2CI2, while with bromine and iodine only the dioxodihalides are formed.
