Revision Notes — Solutions
Key concepts, formulas, and definitions from Solutions for JEE Advanced Chemistry preparation.
Key Topics to Revise
Basic Concepts of Solutions
- Solution = Homogeneous mixture of solute + solvent
- Solvent is present in larger quantity, solute in smaller quantity
- Binary solutions have two components, ternary have three components
Concentration Terms and Calculations
- Molarity (M) = moles of solute per liter of solution
- Molality (m) = moles of solute per kg of solvent
- Mole fraction (X) = moles of component / total moles
Henry's Law and Gas Solubility
- Henry's Law: Solubility of gas ∝ Pressure of gas
- At constant temperature, p = K_H × X (mole fraction form)
- K_H is Henry's constant, depends on gas and solvent nature
Raoult's Law and Vapor Pressure
- Raoult's Law: P_solution = X_solvent × P°_solvent
- Vapor pressure of solution < vapor pressure of pure solvent
- For volatile components: P_A = X_A × P°_A, P_B = X_B × P°_B
