SEPARATION TECHNIQUES - Sepali's Chemistry Guide

SEPARATION TECHNIQUES If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: • the sand stays behind in the filter paper (it becomes the residue) • the water passes through the filter ...

Separation Techniques Key Revision Facts • Distillation can be used to obtain pure water from salt water. The equipment is shown below. Salt water is heated up until it starts to boil, it is then cooled, condensed and collected. The salt is left behind in the flask and the pure water is collected in the flask. • Chromatography is a separation technique used to find out which dyes are in a ...

Chromatographic separation techniques are multi-stage separation methods in which the components of a sample are distributed between 2 phases, one of which is stationary, while the other is mobile. The stationary phase may be a solid or a liquid supported on a solid or a gel. The stationary phase may be packed in a column, spread as a layer, or distributed as a film, etc. The mobile phase may ...
