Question:
A membrane that allows the passage of solvent molecules but not the passage of solute molecules is called ______ membrane.
A membrane that allows the passage of solvent molecules but not the passage of solute molecules is called ______ membrane.
Show Hint
Osmosis occurs only across a semi-permeable membrane.
Updated On: Feb 4, 2026
- differentially permeable
- impermeable
- freely permeable
- semi-permeable
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding membrane permeability.
A semi-permeable membrane allows solvent molecules like water to pass through while restricting solute molecules.
Step 2: Eliminating incorrect options.
Freely permeable membranes allow both solute and solvent, while impermeable membranes allow neither.
Step 3: Conclusion.
Hence, the correct term is semi-permeable membrane.
A semi-permeable membrane allows solvent molecules like water to pass through while restricting solute molecules.
Step 2: Eliminating incorrect options.
Freely permeable membranes allow both solute and solvent, while impermeable membranes allow neither.
Step 3: Conclusion.
