During osmosis, flow of water through a semipermeable membrane is:
Options
- Afrom solution having lower concentration only
- Bfrom solution having higher concentration only
- Cfrom both sides of semipermeable membrane with equal flow rates
- Dfrom both sides of semipermeable membrane with unequal flow rates
Correct answer
D. from both sides of semipermeable membrane with unequal flow rates
Step-by-step solution
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.
