Question

If a mixture of toluene and water is distilled at 97 degree C, what weight of water would be necessary to carry over 1 g of toluene? Compare the operation of a barometer, which is used to measure atmospheric pressure, with that of a mercury manometer, which is used to measure the pressure in an evacuated system. Then a mixture of cyclohexane and toluene is distilled (see Chapter 5), the point of these two miscible liquids is between the boiling points of each of components. By contrast, if a mixture of benzene and water (immiscible) is distilled, the boiling point of the mixture will be below the boiling point pure component. Because benzene and water are essentially insoluble in each

Explanation / Answer

Toluene forms azeotrope with water at 20.2 wt%

thus for a 1 kg toluene we would require = 1000 x 0.202 = 202 ml of water

Mixture would be 202 ml water with 1 kg of toluene in it for distillation
