The above authors from a calculation of the degree of dissociation came to the conclusion that as the dissociation of these compounds increases with the diminution in the concentration of the 3260 S. K. RAY halogen acid they are incapable of independent existence in the absence of either the halogen acid or halogen ions. [...] In the present paper the formation and dissociation of these polyhalides of hydrogen have been studied by the freezing point method and the equilibrium constants of the reactions C+ (12 or Br2) ClI2-or B+ Br Brand the heats of formation of the complexes 0112 ClBr2 and Br3 have been calculated. [...] It is shown that the formation of the polyha logen compounds like HC1I2 HC1Brs HBrs can be definitely established with the aid of the freezing point method and in the case of HBrI2 HBr3 and HI3 the complex compounds have been isolated in the free state. [...] In the following experiments the equilibrium constant has been calculated according to the formula K=— ab c where K is the equlibrium constant ; a b and c are respectively the concentration of the free halogen ions (from the dissociation of the halogen acid) the free halogen and the complex polyhalide ion. [...] The following expression gives the degree of dissociation for the acids _ — 1 a' 1.ON THE STUDY OF POLYHALIDES 261 Any change in the degree of dissociation of the acids by the formation of the complexes is neglected.
