Lowering in vapour pressure is highest for

A

`0.2 m urea`

B

`0.1 m glucose`

C

`0.1 m MgSO_(4)`

D

`0.1 m BaCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`(P^(@)-P_(S))/P^(@)`=Molality `xx (1 - alpha + xalpha +yalpha)`
The value of `P^(@)-P_(S)` is maximum for `BaCl_(2)`.

Lowering of vapour pressure is highest for

Lowering in vapour pressure is a colligative property.

Assertion: Lowering in vapour pressure is not a colligative property. Reason: Lowering of vapour pressure of a solvent depends on the number of moles of the solute dissolved in given amount of the solvent at a given temperature.

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.

The relative lowering in vapour pressure is:

Among the given properties of solution,how many are colligative properties? [Osmotic pressure,Relative lowering in vapour pressure, Boiling point, Elevation in boiling point,Vapour pressure]

What do you mean by relative lowering in vapour pressure ?
