You could describe it in terms of the states of matter visible: SOLID Sand LIQUID Sea GASAirGAS and PLASMASun But as a chemist you might be as...
Crystallisation can be used to separate a solid solute from its solvent. Re-crystallisation is used to purify samples obtained in the laboratory. But what is a crystal?
Students should: 1.10 describe these experimental techniques for the separation of mixtures: simple distillation fractional distillation filtration crystallisation paper chromatography Each technique listed here is a method which can be used for the separation of mixtures of substances. Work through each method in turn . 1.10 Simple distillat...
Filtration can be a simple technique used to separate insoluble solids from a mixture or suspension. It has a lot of everyday applications.
Distillation is used to separate liquids from one another. Visit this page to see distillation in the laboratory and look at an industrial scale process.
