simple separation

• Titration


  Find out amount of acid needed to neutralise given alkali
• As temperature increases

  Solid becomes more soluble
• Measuring maximum mass of solute

  1. Dissolve solute in 100g water

  2. Reweigh filtered, dried solid
• Saturated solution


  Maximum mass of solute that can be dissolved in 100g water
• Chromatography


  Separate a mixture (soluble)
• Simple distillation


  Separate liquid/solvent from solution
• Fractional distillation


  Separate liquid mixture, liquid impurity

  • separate oxy from liquid air (nitrogen, oxygen close in bp)
• Filtration


  Separate insoluble solid from liquid
• Crystallisation


  Separate soluble solid from solution
