Topics in Solutions

1

Types of Solutions and Solubility

  • Solutions are homogeneous mixtures of solute and solvent in various physical states
  • Nine types of solutions exist based on states: solid-solid (alloys), liquid-liquid (ethanol-water), gas-liquid (CO₂-water), etc.
  • Saturated solution contains maximum solute at given temperature; supersaturated contains excess solute
2

Raoult's Law and Vapour Pressure

  • Raoult's Law: Partial vapour pressure of component = vapour pressure of pure component × mole fraction
  • For binary solutions: P₁ = x₁P₁⁰ and P₂ = x₂P₂⁰
  • Total pressure P = P₁ + P₂ = x₁P₁⁰ + x₂P₂⁰
3

Colligative Properties - Vapour Pressure Lowering

  • Colligative properties depend only on number of solute particles, not their nature
  • Four colligative properties: vapour pressure lowering, boiling point elevation, freezing point depression, osmotic pressure
  • Vapour pressure lowering occurs when nonvolatile solute is dissolved in volatile solvent
4

Boiling Point Elevation and Freezing Point Depression

  • Boiling point elevation occurs because solution has lower vapour pressure than pure solvent
  • Solution must be heated to higher temperature to reach atmospheric pressure for boiling
  • Freezing point depression occurs because solute molecules interfere with crystal formation
