Which of the aqueous equimolal solution ...

Which of the aqueous equimolal solution will have its vapour pressure near to solvent ?

A

Urea

B

`Ba(NO_3)_2`

C

`NaNO_3`

D

`Al(NO_3)_3`

Text Solution

Verified by Experts

The correct Answer is:
A
`(p^@-p_s)/p^@=n/(n+N)i`, `DeltaP` is minimum since i=1 for urea. Thus, urea solution will have its vapour pressure closer to solvent.
