Consider the figure and mark the correct option.

Options

A. a) Water will move from side (A) to side (B) if a pressure lower than osmitic pressure is applied on piston(B)
B. b) Water will move from side (B) to side (A) if a pressure greater than osmotic pressure is applied on postion (B)
C. c ) Water will move from side (B) to side (A) if a pressure equal to osmotic pressure is applied on pistion (B)
D. d ) Water will more from side (A) to side (B) if pressure equal to osmotic pressure is applied on piston (A)

Answer

B

Explanation

We know that, if a pressure higher than the osmotic pressure is applied on the solution the solvent will flow from the solution into the pure solvent through the semi-permeable membrane. This process is called reverse osmosis.
Thus in this case, water will move form side (B) to side (A) it a pressure greater than osmotic pressure is applied on piston (B).
