Question
Van′t Hoff factors of aqueous solutions of X, Y, Z are 1.8, 0.8 and 2.5. Hence, their (assume equal concentrations in all three cases)
Options
A.b.p. : X < Y < Z
B.f. p. Z < X < Y
C.osmotic pressure : X = Y = Z
D.v. p. : Y < X < Z
Solution
As van′t Hoff factor increases RLVP increases i.e., V.P. decreases y > x > z
Elevation in b.p. increases i.e., b.p. increases y < x < z
Depresion in f.p increases i.e., f.p decreases y > x > z
Osmotic pressure increases so y < x < z.
Elevation in b.p. increases i.e., b.p. increases y < x < z
Depresion in f.p increases i.e., f.p decreases y > x > z
Osmotic pressure increases so y < x < z.
