Key Topics to Revise

1

Ammonia (NH₃) and Haber Process

  • Ammonia is a colorless gas with pungent smell and basic nature
  • Laboratory preparation: 2NH₄Cl + Ca(OH)₂ → CaCl₂ + 2H₂O + 2NH₃
  • Industrial production by Haber process at high pressure (200 atm), high temperature (450°C) using Fe catalyst
2

Sulphuric Acid (H₂SO₄) and Contact Process

  • Called 'King of Chemicals' due to extensive industrial applications
  • Contact process involves four main steps with V₂O₅ catalyst
  • Step 1: S + O₂ → SO₂ (burning sulphur)
3

Sodium Hydroxide (NaOH) and Chlor-Alkali Process

  • Also known as caustic soda, strong base with formula NaOH
  • Produced industrially by chlor-alkali process (electrolysis of brine)
  • At anode: 2Cl⁻ → Cl₂ + 2e⁻ (oxidation)
4

Hydrochloric Acid (HCl) and Properties

  • Strong monobasic acid: HCl → H⁺ + Cl⁻
  • Industrial preparation: H₂ + Cl₂ → 2HCl (direct combination)
  • HCl gas dissolved in water forms hydrochloric acid solution
