Question:
In case of association, abnormal molar mass of solute will:
In case of association, abnormal molar mass of solute will:
Show Hint
In case of association, the abnormal molar mass tends to decrease due to the aggregation of solute molecules.
Updated On: Feb 28, 2025
- increase
- decrease
- remain same
- first increase and then decrease
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding association.
In case of association, solute molecules aggregate, resulting in a reduction in the number of particles in the solution. This causes the molar mass to appear lower than the expected value.
Step 2: Conclusion. Thus, the abnormal molar mass decreases in case of association, corresponding to option (B).
Step 2: Conclusion. Thus, the abnormal molar mass decreases in case of association, corresponding to option (B).
