Separating Mixtures and Crystallisation

Start with solutions and mixtures

Begin with the mind map Chemistry Solutions and Mixtures. It compares mixtures and compounds, including whether their elements are chemically joined. Use it to establish the difference before moving on to ways of separating mixtures.

Next, try the flashcards in Solution and crystallisation. They cover terms including solute, solvent, solution, concentrated and dilute solution, and crystallisation. Say what each term means before checking the card. Return to any terms that are hard to distinguish.

Explore separation techniques

Solutions Separation Techniques Outcomes asks about evaporation, condensation, crystallisation and distillation. It also includes questions asking for examples. Work through the definitions first, then use the example questions to practice identifying the techniques.

For a wider set of methods, use Other Separation Techniques Outcomes. Its questions cover centrifugation, electrostatic separation, sieving, magnetism, chromatography and adsorption. Compare the questions with the earlier deck and note which methods you need to study again.

Bring the ideas together

The mind map Solubility and purification of water includes solubility curves and how different amounts of substances can dissolve at different temperatures. It can help connect the terms in the flashcards to the wider Solutions and Solubility unit in Chemistry.

This page has no quizzes, but you can turn points from a mind map into quiz questions and check your answers against the map. Then use the flashcards to revisit definitions or methods you missed. Pick a map and build a short set of questions from it.
