Study the following figure, and select the correct statements. A. There will be no mevement of any solution across the membraneB. Water from `BaCl_(2)` will flow towards the `NaCl` solutionC. Water from `NACl` will flow towards the `BaCl_(2)`D. The osmotic pressure of `0.1 M NaCl` is higher than the osmotic pressure of `0.05 M BaCl_(2)`, assuming complete dissociation of the electrolyte

Answer» Correct Answer - B::D
`pi = I CRT`
Assuming complete dissociation
`pi_(NaCl) = 2 xx 0.1 RT = 0.2 RT`
`pi_(BaCl_(2)) = 3 xx 0.05 xx RT = 0.15 RT`
`:. pi_(NaCl) gt pi_(BaCl_(2))`
`rArr` Water (solvent) will move from `BaCl_(2)` towards `NaCl` solution.
