METHODS of SEPARATING MIXTURES

 Doc Brown's Chemistry KS4 science GCSE/IGCSE/O Level Chemistry Revision Notes

ELEMENTS, COMPOUNDS, MIXTURE  separation, CHEMICAL REACTIONS & EQUATIONS

dissolving-stirring, filtering, evaporation, crystallising diagram of paper/thin layer chromatography at the end diagram of paper/thin layer chromatography at start

PART 2 Methods of separating mixtures are described e.g. ways of separating liquids, simple distillation, fractional distillation, paper chromatography, thin layer chromatography, filtration, evaporation, crystallisation, separating funnel, decantation, centrifuge, centrifuging, decanting-decantation, instrumental methods of analysis, glc gas-liquid chromatography, purifying substances - index of keywords-terms-phrases below

Part 1 Definitions in Chemistry, Elements, Compounds

and Mixture pictures & Physical & Chemical Changes

Part 2 Methods of Separating Mixtures of Substances (index further down page)

Part 3 How to write equations, work out formula and name compounds

INDEX of METHODS of SEPARATING MIXTURES and purifying substances pages

The original 'huge' page has now been split into 4 separate pages accessed by the 4 links below

Many of these procedures are important in the isolation and purification of desired products from chemical reactions


DISTILLATION 2.1 Simple Distillation  *  2.2 Fractional Distillation


 

CHROMATOGRAPHY 2.3 Paper/Thin Layer Chromatography and 2.6 Gas Chromatography


2.4a FILTRATION  2.4b EVAPORATION  2.4c CRYSTALLISATION 2.4 DECANTATION

2.4 Four techniques used in a particular and separation and purification procedure

e.g. How can we separate a mixture of sand and salt?, separating a salt from a salt preparation?


  

2.5 Miscellaneous Separation Methods and other apparatus uses

Separating funnel, magnet, solvent extraction, centrifuge
