Zur Calorimetrie der Bismutoxidhalogenide. II. Bismutoxidbromide

Calorimetry of Bismuth Oxidhalides. II. Bismuth Oxidebromides The heat solution of all known solid phases in the system Bi₂O₃/BiBr₃ in 4n HBr were investigated. To compare the data they were converted to the standardized formula Bi₂O_3?y/2Br_yBr_y with 0 ? y ? 2. The enthalphies of formation of the complex bismuthoxidebromides are based on the enthalpies of Bi₂O_3,f HBr_,Lsg and H₂O circumventing the value for Bi(OH)_3,Lsg.
