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`

Which of the following aqueous solutions should have the highest boiling point ?

A

1.0 M NaOH

B

1.0 M `Na_2S0_4`

C

1.0 M `NH_4NO_3`

D

1.0 M `KNO_3`

Text Solution

Verified by Experts

The correct Answer is:
B
` Na_2SO_4` will release 3 moles of ions moles of `Na_2SO_4` in the aqueous solution and Boiling point being a colligative property, the Boiling point of this solution will be the highest as other solutions release only 2 ions each .
