The ebulliometric technique for determination of infinite-dilution activity coefficients is examined. A simple mathematical model of ebulliometer is formulated to derive and analyze corrections accounting for the difference between the composition of the ebulliometer charge and that of the equilibrium liquid. Our own experimental equipment employing the comparative ebulliometric setup is described along with the measuring procedure and calibration. Error analysis is carried out identifying major factors limiting the accuracy of the determination.
