Abstract
The conductivity and vapor pressure data of the system calcium-oxide–sulphur-dioxide–water presented in an earlier paper have been used to calculate ionic concentrations existing in this system, in the temperature and pressure range investigated. Two methods of calculation have been employed, one depending on the combination of vapor pressure and conductivity data, and the other, on conductivity data. For both, recourse was had to the data of Campbell and Maass on the system sulphur-dioxide–water. These methods gave results that are in good agreement with each other. The existence of a complex CaSO3.Ca(HSO3)2 was deduced.Hydrogen ion concentrations over the concentration and temperature range investigated have been calculated and extrapolations made to higher temperatures. These are presented in tabular form. Apart from the theoretical interest, it is pointed out that these results are of value in connection with studies of the delignification of wood by calcium-oxide–sulphur-dioxide–water solutions.
