Topics in Ionic Equilibrium

1

Concepts of Acids and Bases

  • Three main theories: Arrhenius, Brønsted-Lowry, and Lewis concepts
  • Arrhenius concept limited to aqueous solutions only
  • Brønsted-Lowry concept involves proton transfer reactions
2

Ionization Constants and Strength of Acids and Bases

  • Strong acids/bases ionize completely (Ka or Kb >> 1)
  • Weak acids/bases ionize partially (Ka or Kb << 1)
  • Higher Ka value means stronger acid
3

Ionic Product of Water and pH Scale

  • Pure water undergoes auto-ionization: 2H₂O ⇌ H₃O⁺ + OH⁻
  • Kw = [H₃O⁺][OH⁻] = 1.0 × 10⁻¹⁴ at 25°C
  • In pure water: [H₃O⁺] = [OH⁻] = 1.0 × 10⁻⁷ M
4

Common Ion Effect

  • Addition of common ion suppresses ionization of weak electrolyte
  • Based on Le Chatelier's principle
  • Degree of ionization decreases in presence of common ion
