Key Topics to Revise
1
Types of Solutions and Concentration Units
- Solutions can be gaseous (O₂ + N₂), liquid (ethanol in water), or solid (brass alloy)
- Mass percentage = (mass of solute/mass of solution) × 100
- Volume percentage used for liquid-liquid solutions like alcohol-water mixtures
2
Henry's Law and Gas Solubility
- Henry's law: Solubility of gas ∝ pressure of gas above solution
- Mathematical form: m = KP or p = KHχ where KH is Henry's constant
- Higher KH value means lower gas solubility in liquid
3
Raoult's Law and Vapor Pressure
- Raoult's law: PA = χA × P°A for each component in solution
- Total pressure: PT = PA + PB = χA·P°A + χB·P°B
- Vapor pressure lowering: ΔP = χsolute × P°solvent
4
Colligative Properties - Boiling Point Elevation and Freezing Point Depression
- Colligative properties depend only on number of solute particles, not their identity
- Boiling point elevation: ΔTb = Kb × m where Kb is ebullioscopic constant
- Freezing point depression: ΔTf = Kf × m where Kf is cryoscopic constant
