  • chromatography is used to separate mixtures of substances in a liquid
  • chlorination is the process of adding chlorine to water to kill bacteria
  • sedimentation is the process of particles settling out of a liquid to a solid
  • filtratrion is the process of separating a solid from a liquid by passing it through a filter
  • distillation is used to separate a solvent from a solute
  • crystallisation is used to separate a soluble solid from a solution
  • pure water is a solution of H2O in which no other substances are present
  • potable water is water that is safe to drink and is free from harmful bacteria
  • soluble : a substance that can be dissolved
  • solvent : a liquid that can dissolve a substance in it
  • solution : a mixture of two or more substances that are dissolved in each other
  • miscible : liquids that can be mixed together
  • immiscible : two liquids that do not mix together
  • movement and arrangement : solids
    M - vibrates rapidly
    A - tightly packed together, uniform arrangement
  • movement and arrangement : liquids
    M - flows more freely, will change shape to fit a container
    A - more spread out arrangement, particles flow over eachother
  • movement and arrangement : gases

    M - particles move around freely, spread out far apart to fill a container
    A - particles are arranged very sparsely, not touching often
