Standard separation techniques for mixtures: WAEC Chemistry Past Questions and Answers

What the WAEC syllabus covers in Standard separation techniques for mixtures

Our summary: The kinds of mixtures, the methods used to separate them, and how to tell when a substance is pure.

  • Classification of mixtures (Solid-solid, solid-liquid, liquid-liquid, gas-gas with examples.)
  • Separation techniques (Crystallization, distillation, precipitation, magnetization, chromatography, sublimation etc.)
  • Criteria for purity (Boiling point for liquids and melting point for solids.)
