Question

0.1 M NaCl and 0.05 M B a C l 2 solutions are separated by a semi- permeable membrane in container. For this system, choose the correct answer, Water flows form B a C l 2 solution towards NaCl solution, There is no movement of any solution across the membrane, Osmotic pressure of 0.1 M NaCl is lower than the osmotic pressure of B a C l 2 (Assume complete dissociation), Water flows from NaCl solution towards B a C l 2 solution

Using π V = i C R T i = 2 for NaCl i = 3 for B a C l 2 π V N a C l = 2 × 0.1 R T = 0.2 R T π V B a C l 2 = 3 × 0.05 R T = 0.15 R T As π V N a C l > π V B a C l 2 . Here water flows from B a C l 2 towards N a C l solution.
