1. Separating Mixture

   • Filtration
     • Separates an insoluble solid from a liquid
     • Equipment
       • Funnel,filter, paper,conical flask
     • Residue
       • the solid left in the filter paper
     • Filtrate
       • the liquid that passes through the filter paper
   • Crystallisation
     • Separates a soluble solid from a liquid
     • equipment
       • Evaporating basin, heat
     • Evaporation
       • the liquid turns to a gas and leaves crystals of the solid behind
   • Chromatography
     • Separates link & food colours
       • Stationary phase
         • paper
     • RF value
       • Mobile phase
         • Solvent water
   • Distillation
     • separates two liquid with boiling Points
       • Equipment
         • round bottomed flask , heat ,condenser. beaker
     • evaporation of one liquid happens in the round bottomed flask
       • the vapour condenses in the condenser and collects in the beaker
         • the other liquid doesn't evaporate and stays in the round bottomed flask
