A) Water flows from\[BaC{{l}_{2}}\]solution towards NaCl solution.
B) There is no movement of any solution across the membrane.
C) Osmotic pressure of 0.1 M NaCl is lower than the osmotic pressure of \[BaC{{l}_{2}}\](Assume complete dissociation).
D) Water flows from NaCl solution towards \[BaC{{l}_{2}}\]solution.
Correct Answer: A
Solution :
Using \[\pi V=iCRT\] \[i=2\]for NaCl. \[i=3\]for \[BaC{{l}_{2}}.\] \[\pi {{V}_{NACl}}=2\times 0.1\,RT=0.2\,RT.\] \[\pi V\,BaC{{l}_{2}}=3\times 0.05\,RT=0.15\,RT.\] As \[\pi {{V}_{NaCl}}>\pi {{V}_{BaC{{l}_{2}}.}}\]Here water flows from \[Bac{{l}_{2}}\]towards\[NaC{{l}_{2}}\]solution. Hence, the correct option is [a].
