Which of the following statement are correct ?

Options

A. The increasing order of osmotic pressure of 0.1M aqueous solution is as follows 0.1M Glucose `lt 0.1M` Sodium chloride `lt 0.1M` Magnesium chloride.
B. Density of a solution in independent of temperature
C. Camphor has comparatively larger value of `K_(f)` as compared to other common solvents
D. Limiting value of van't Hoff factor of `K_(4)[Fe(CN)_(6)]` is 11.

Answer

A, C

Explanation

(A) The total concentration of species of `MgCl_(2)` solution will be 0.3M and in NaCl solution it will be 0.2 M. Glucose in a nonelectrolyte, hence concentration of glucose solution will be 0.1M
(B) Density is defined as mass per unit volume and the volume of the solution varies with temperature
(D) In solution, `K_(4)Fe(CN)_(6)` ionizes as `K_(4)Fe(CN)_(6) hArr 4k^(+) + Fe(CN)_(6)^(4-)`. Hence, the limiting vlaue of vant.s Hoff factor will be 5.
