Lowering of vapour pressure is highest for

A

0.1 M `BaCl_(2)`

B

0.1 M glucose

C

0.1 M `MgSo_(4)`

D

urea

Text Solution

Verified by Experts

The correct Answer is:
a
Lowering of vapour pressure is directly proportional to the van't Hoff factor. For `BaCl_(2)`, I = 3 (maximum) thus, `BaCl_(2)` has highest value for relative lowering of vapour pressure.

Lowering in vapour pressure is highest for

Statement The vapour pressure of 0.45 molar urea solution is more than that of 0.45 molar solution of sugar. Explanation Lowering of vapour pressure is directly proportional to the number of species present in the solution.

STATEMENT-1 : Relative lowering of vapour pressure is equal to mole fraction of the solute. and STATEMENT-2 : Relative lowering of vapour pressure is a colligative property.

The vapour pressure of a pure liquid at 25^(@)C is 100 mm Hg. Calculate the relative lowering of vapour pressure if the mole fraction of solvent in solution is 0.8.

The law of relative lowering of vapour pressure was given by

Assertion:Lowering of vapour pressure is not dependent on the number of species present in the solution. Reason : Lowering of vapour pressure and relative lowering of vapour pressure are colligative properties
