Question

During osmosis, flow of water through a semipermeable membrane is

• A. from solution having lower concentration only
• B. from solution having higher concentration only
• C. from both sides of semipermeable membrane with equal flow rates
• D. from both sides of semipermeable membrane with unequal flow rates

Answer 1

The correct option is D from both sides of semipermeable membrane with unequal flow rates

Osmosis is the phenomenon of flow of pure solvent from the solvent to the solution or from a less concentrated solution to a more concentrated solution through a semipermeable membrane. Common semipermeable membranes are permeable to certain solute particles also. Infact, there is no perfect semipermeable membrane. Therefore, we can say that flow of water through a semipermeable membrane takes place both sides with unequal rates.
