Some possible Revision notes for the chapter "Solutions" in Class 12 Chemistry are:
1. Solutions: A solution is a homogeneous mixture of two or more substances.
2. Concentration: Concentration is the amount of solute present in a given quantity of solvent or solution.
3. Types of Solutions: There are three types of solutions - solid solutions, liquid solutions, and gaseous solutions.
4. Expressing the Concentration of Solutions: Concentration of a solution can be expressed in various ways like molarity, molality, normality, percentage, parts per million (ppm), and parts per billion (ppb).
5. Solubility: Solubility is the maximum amount of solute that can dissolve in a given quantity of solvent at a particular temperature and pressure.
6. Factors Affecting Solubility: Solubility of solute in a solvent is affected by temperature, pressure, and nature of solute and solvent.
7. Raoult's Law: According to Raoult's law, the vapor pressure of a component in a solution is proportional to its mole fraction in the solution.
8. Henry's Law: Henry's law states that the amount of gas dissolved in a liquid is directly proportional to the partial pressure of the gas above the liquid.
9. Colligative Properties: Colligative properties are those properties of solutions that depend upon the number of solute particles but not on their nature.
10. Types of Colligative Properties: The four types of colligative properties are vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
11. Osmosis: Osmosis is the flow of solvent from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane.
12. Reverse Osmosis: Reverse osmosis is the process of removing impurities from water by applying pressure to force the water molecules through a semipermeable membrane.
13. Electrolytes: Electrolytes are substances that produce ions when dissolved in water.
14. Non-electrolytes: Non-electrolytes are substances that do not produce ions when dissolved in water.
15. Strong and Weak Electrolytes: Strong electrolytes completely dissociate into ions when dissolved in water while weak electrolytes partially dissociate into ions when dissolved in water.
