Abstract
The boiling point elevation of various aqueous solutions containing sodium chloride, potassium chloride, sodium sulfate, sodium carbonate, calcium chloride and magnesium chloride were measured by using a twin-type ebulliometer in the weight per cent range of 1% to 15% under the atmospheric pressure, and very accurate data were obtained there from.
The B. P. E. data of each aqueous solution containing an inorganic salt were correlated with the weight per cent of the salt for three equations. The constants of the three equations for each solution were determined by the least square method. The best equation for smoothing the B. P. E. data was cubic equation of the weight per cent of each inorganic salt.
The boiling point elevations calculated from the cubic equation were approximated to experimental values with high degree of accuracy.
