Question

Some statements are given below
for the same solution `Delta T_(b) =Delta T_(f)`
5% solution of urea will have more osmotic pressure than 10% solution of glucose
elevation of B. pt. is due to increase in vapour pressure of solution on adding solute
depression of F.pt. is due to decrease in vapoure pressure of solution on adding solute. Among the above
A. B and D are true
B. A,B & D are false
C. B and C are false
D. only D is true

Answer 1

Correct Answer - D
(A) False. As for a given solvent `K_(b) and K_(f)` are not equal. (B) True.as urea solution has higher molarity than glucose solution.
`pi = MRT or `pi = CRT where` C = "molarity of solution" " As" R and T are constants `pi alpha M` (c) False. It is due to lowering of V.P. (D) True.
