  • Ionic Equations and Precipitation
    • Insoluble product-precipitate
    • Extremely high collision frequency
      • Very fast reactions: insoluble product formed instantly
    • Equation summarised: AB+CD ---> AD+BC
      • e.g. Barium chloride+sodi-um sulphate ---> Barium sulphate+sod-ium chloride
    • Spectator ions-do not take part in the reaction
    • Salts- Mix solutions, filter, wash sample, dry (evaporation)
