Acetic acid dimerises in benzene. The depression in freezing pomt of 0.2 molal acetic acid in benzene solution is 0.55 K. The degree of association of acetic acid in Benzene is numerically equal to degree of ionisation of MgSO4 in water of 2.0 molal concentration. Boiling point of the aqueous solution is
(Kf Benzene = 5.0 K‌kg‌mol−1, Kb water = 0.5 K‌kg‌mol−1, boiling point of water 100.15°C)
