In part ‒ I and part ‒ II of CBSE Class 12 Chemistry: Chapter Notes on Solutions, we have covered important concepts like definition of solution, types of solutions, various ways to express concentration of solution, solubility, solubility of solid in a liquid, vapour pressure of different types of solution, ideal & non-ideal solutions, Raoult's law, azeotropes etc and solved conceptual questions based on them.
Now we will study the following topics and questions based on them:
o Colligative Properties
- Relative lowering of vapour pressure of solvent
- Elevation in boiling point
- Depression in Freezing point
- Osmotic pressure
o Isotonic solution
o Hypertonic solution
o Hypotonic solution
o Reverse Osmosis
o Abnormal Molar Masses
The notes given below on above mentioned are very important for CBSE board exams as well as competitive exams.
Colligative Properties and Determination of Molecular Masses
On the basis of concentration of solution on both side of semi permeable membrane, solution can be classified as:
Abnormal Molar Mass
