Q - 0.10M NaCl 0.05 M BaCl2 solutions are separated by a semi permeable membrane in a container . for a system , choose the correct answer
a] there is no movement of any solution across the membrane
b ] water flows from BaCl2 solution towards NaCl solution
c] water flow from NaCl solution to BaCl2 solution
d ] osmotic pressure pressure of 0.1 M NaCl is lower than the osmotic pressure of BaCl2
EXPERTSfor these type of Questions molarity is considered or normality is considered ?
Since osmosis occurs in the direction from less concentrated solution to more concentrated solution. Therefore solvent will flow from less concentrated solution towards more concentrated i.e Water flows from BaCl2 solution towards NaCl.
Ans (b)
d is incorrect because osmotic pressure is directly proportional to the molarity.
Therefore NaCl will have greater osmotic pressure than BaCl2.
In general, Molarity is used instead of normality.
