A solution of two liquids boils at a temperature more than the boiling point of either of them. Hence, the binary solution shows

A

negative deviation from raoult's law

B

positive deviation from raoult's law

C

no deviation from raoult's law

D

positive or negative deviation from raoult's law depending upon the composition.

Text Solution

Verified by Experts

The correct Answer is:
A
The vapour pressure of the solution is lower than that of either of two liquids. Hence, the solution shows negative deviation from raoult's law.

An aqueous solution containing urea was found to have boiling point more than the normal boiling point of water (373.13 K). When the same solution was cooled it was found that its freezing point is less than the normal freezing point of water (273.13 K). Explain these observations.

  • Read the passage given below and answer the following questions : Raoult's law states that for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in solution. Dalton's law of partial pressure states that the total pressure P_("total") over the solution phase in the container will be the sum of the partial pressures of the components of the solution and is given as: P_("total") = P_1 + P_2 A solution of two liquids boils at a temperature more than the boiling point of either of them.
