1. Define a solution. What are its different types based on the solute and solvent?
2. Explain the concept of mole fraction. How is it used in the calculation of solution concentration?
3. What is Raoult’s Law? Explain its application in calculating vapor pressure of a solution.
4. Differentiate between ideal and non-ideal solutions with suitable examples.
5. How does the addition of a non-volatile solute affect the boiling point and freezing point of a solvent?
6. What are colligative properties? Name and briefly explain the four colligative properties.
7. Define the term 'osmotic pressure'. How is it related to the concentration of solute particles?
8. Explain the phenomenon of reverse osmosis. Where is it used?
9. Calculate the molality of a solution containing 50g of glucose (C6H12O6) dissolved in 400g of water.
10. What is the van't Hoff factor (i)? How is it used to explain the degree of dissociation in electrolytic solutions?
These questions cover various key concepts from the chapter and will help students understand and apply the principles of solutions.
