Question

Based on the figure given which of the following statements is not correct?

• A. Movement of solvent molecules will take place from chamber A to B
• B. Movement of solute will take place from A to B
• C. Presence of a semi-permeable is a pre-requisite for this process to occur
• D. The direction and rate of osmosis depends on both the pressure gradient and concentration gradient

Answer 1

The correct option is B Movement of solute will take place from A to B

The water in the chamber A has less amount of solute particles and hence the water potential in chamber A is higher so the water molecules in chamber A can move easily. Therefore the solvent molecules or the water molecules will move from chamber A to B. Since the membrane between the chambers is semi-permeable, the solute molecules cannot move from A to B or B to A.

So the correct option is 'movement of solute will take place from A to B'
