Solution

The correct option is A A,R
(A)
$π_{1} : 0.1 M glucose \Rightarrow i = 1 {for non- elecrolyte i = 1}$
$π_{2} : 0.1 M Urea \Rightarrow i = 1$
$π_{1} : CRT = 0.1 R T$
$π_{2} : CRT = 0.1 R T$
$π_{1} = π_{2} (π_{1} and π_{2} isotonic)$
$So, no net migration of solvent across the membrane.$

(B)
$π_{1} : 0.1 M N a C l \Rightarrow i = 2$
$π_{2} : 0.1 M N a_{2} S O_{4} \Rightarrow i = 3$
$π_{1} : i C R T = 2 \times 0.1 R T = 0.2 R T$
$π_{2} : 0.1 \times 3 R T = 0.3 R T$
$π_{1} < π_{2}$
$π_{1} hypotonic to π_{2} .$

(C)
$π_{1} : 0.1 M N a C l \Rightarrow i = 2$
$π_{2} : 0.1 M K C l \Rightarrow i = 2$
$π_{1} = π_{2} = 2 \times 0.1 R T = 0.2 R T$
$π_{2} & π_{2} isotonic$
$So, no net migration of solvent across the membrane.$

(D)
$π_{1} : 0.1 M C u S O_{4} \Rightarrow i = 2$
$π_{2} : 0.1 M Sucrose \Rightarrow i = 1$
$π_{1} : 2 \times 0.1 R T = 0.2 R T$
$π_{2} : 2 \times 0.1 R T = 0.1 R T$
$π_{1} > π_{2}$
$So π_{1} is hypertonic to π_{2}$
