Question

Based on the figure given below 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

Answer: (B)

Solution $A$ and solution $B$ are separated by a semipermeable membrane. Solution $A$ has higher water potential. Therefore, osmotic movement of water molecules (solvent molecules) will occur from solution $A$ to $B$. Solute particles cannot pass through semi-permeable membrane.
