The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Isotonic solutions are defined based on their behavior across a semi-permeable membrane.
Step 3: Detailed Explanation:
Two solutions are said to be isotonic if they have the same osmotic pressure at the same temperature.
If two solutions are isotonic, there is no net movement of solvent between them when they are separated by a semi-permeable membrane.
Mathematically, for isotonic solutions 1 and 2:
\[ \Pi_1 = \Pi_2 \]
\[ i_1 C_1 R T = i_2 C_2 R T \]
where \(C\) is molarity and \(i\) is the van't Hoff factor.
Step 4: Final Answer:
Isotonic solutions have identical osmotic pressure.
