Abstract
Vapour pressures of aqueous solutions of the mixed melt AgNO3 + TlNO3 + Cd(NO3)2 have been measured at 98.5 °C by the static technique. The Ag/Tl mole ratio was fixed at 1.06, and the mole fractions Cd/(Ag + Tl + Cd) of Cd in the melt were 0, 0.05, 0.075, 0.10, and 0.125. Adapted BET isotherms and their constants were obtained for each of the five melt mixtures. It has been shown, in the present study, from the BET equation itself, and verified experimentally, that certain Systems can give rise to a 'crossover point', that is, a reversal of sign of the deviation from Raoult's law. The BET constants of the systems conform to simple additivity rules. The water concentration range over which the BET equation is valid is unexpectedly wide.
