Flow of Water Across a Semipermeable Membrane
When two solutions of different osmolarity are separated by a semipermeable membrane, the movement of water molecules is dependent on the concentration of solutes in the solutions. The following are the possible scenarios:
1. Hypotonic Solution:
A hypotonic solution has a lower concentration of solutes compared to the other solution. When a hypotonic solution and a hypertonic solution are separated by a semipermeable membrane, the water molecules move across the membrane from the hypotonic solution to the hypertonic solution. This movement of water molecules is known as osmosis. The hypertonic solution becomes more diluted, and the hypotonic solution becomes more concentrated.
2. Hypertonic Solution:
A hypertonic solution has a higher concentration of solutes compared to the other solution. When a hypertonic solution and a hypotonic solution are separated by a semipermeable membrane, the water molecules move across the membrane from the hypotonic solution to the hypertonic solution. This movement of water molecules is known as osmosis. The hypertonic solution becomes more concentrated, and the hypotonic solution becomes more diluted.
3. Isotonic Solution:
An isotonic solution has an equal concentration of solutes compared to the other solution. When an isotonic solution and another solution are separated by a semipermeable membrane, there is no net movement of water molecules across the membrane. The concentration of solutes in both solutions remains the same.
Conclusion
In conclusion, when two solutions of different osmolarity are separated by a semipermeable membrane, the movement of water molecules across the membrane is dependent on the concentration of solutes in the solutions. The flow of water will always take place from a hypotonic solution to a hypertonic solution. Therefore, option A is the correct answer.
