0.1 M NaCl and 0.05 M BaCl(2) solutions ...

0.1 M NaCl and 0.05 M `BaCl_(2)` solutions are separated by a sami-premeable membrane in a container. For this system, choose the correct answer

A

There is no movement of any solution across the membrane

B

Water flows from `BaCl_(2)` solution towards NaCl solution

C

Water flows from NaCl solution towards `BaCl_(2)` solution

D

Osmotic pressure of 0.1 M NaCl is lower than the osmotic pressure of `BaCl_(2)` (Assume complete dissociation)

Text Solution

Verified by Experts

The correct Answer is:
B
Applying `piV=iCRT`
i = 2 for NaCl
i = 3 for `BaCl_(2)`
`piV_(NaCl)=2xx0.1RT=0.2RT`
`piV_(BaCl_(2))=3xx0.05RT=0.15RT`
As `piV_(NaCl)gtpiV_(BaCl_(2))`. So, water flows from `BaCl_(2)` towards NaCl solution.
