If benzene. Toluene and para-xylene are ...


If benzene. Toluene and para-xylene are mixed in molar ratio 1:2:3.
Then answer the following question carefully.
Estimate the dew point pressure (At the dew point pressure all liquid vaporiaed ) for the above mixture (approximately)

A

180 torr

B

152 torr

C

138 torr

D

156 torr

Text Solution

Verified by Experts

The correct Answer is:
B
At the dew point pressure all liquid vaporized
`(1)/(P_(("dew point")))=[(Y_(B))/(P_(B)^(@))+(y_(T))/(P_(T)^(@))+(Y_(X))/(P_(X)^(@))]" " (Y_(B)=(1)/(6), Y_(T)=(2)/(6), Y_(X)=(3)/(6))`

In the study of titration of NaOH and Na_(2)CO_(3) . NaOH and NaHCO_(3) , Na_(2)CO_(3) and NaHCO_(3) , phenophthalein and methyl orange are used as indicators. (a). When phenolphthalein is used as an indicator for the above mixture: (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaHCO_(3) is formed at the end point. (b). When methyl orange is used as an indicator for the above mixture (i).

Properties such as boiling point, freezing point and vapour pressure of a pure solvent change when solute molecules are added to get homogeneous solution. These are called colligative properties. Applications of colligative properties are very useful in day-to-day life. one of its examples is the use of ethylene glycol adn water mixtures as anti-freezing liquid in the radiator of automobiles. A solution M is prepared by mixing ethanol and water. The mole fraction of ethanol in the mixture is 0.9 . Given: Freezing point depression constant of water (K_(f)^(water)) = 1.86 K kg mol^(-1) Freezing point depression constant of ethanol (K_(f)^("ethanol")) = 2.0 K kg mol^(-1) Boiling point elevation constant of water (K_(b)^(water)) = 0.52 K kg mol^(-1) Boiling point elevation constant of ethanol (K_(b)^("ethanol")) = 1.2 K kg mol^(-1) Standard freezing point of water = 273 K Standard freezing point of ethanol = 155.7 K Standard boiling point of water = 373 K Standard boiling point of ethanol = 351.5 K Vapour pressure of pure water = 32.8 mm Hg Vapour pressure of pure ethanol = 40 mm Hg Molecular weight of water =18 g mol^(-1) Molecular weight of ethanol = 46 g mol^(-1) In answering the following questions, consider the solutions to be ideal dilute solutions and solutes to be non-volatile and non-dissociative.
