Equal volumes of 0.1 M NaCl and 0.06 M CaC l 2 solutions are separated by a semi- permeable membrane in container. For this system, choose the correct answer
Options
- AWater flows from NaCl solution towards CaC l 2 solution
- BThere is no movement of any solution across the membrane
- COsmotic pressure of 0.1 M NaCl is lower than the osmotic pressure of CaC l 2 (Assume complete dissociation)
- DWater flows form CaC l 2 solution towards NaCl solution
Correct answer
D. Water flows form CaC l 2 solution towards NaCl solution
Step-by-step solution
Using π V = iCRT i = 2 for NaCl i = 3 for CaC l 2 π V NaCl = 2 × 0 . 1RT = 0 . 2RT π V C a C l 2 = 3 × 0.0 6RT = 0 . 18RT As π V NaCl > π V C a C l 2 . Here water flows from CaC l 2 towards NaCl solution.
