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 physical separation procedures are important in the isolation and purification of desired products from chemical reactions - they are important techniques to know about.

REMINDERS: A MIXTURE is a material made up of at least two substances which may be elements or compounds physically mixed together but are NOT chemically combined together.

So the elements and compounds retain their original chemical properties i.e. components of a mixture retain their individual chemical properties, and this is very important when considering formulations.

Components of a mixture can be separated by physical means and these methods are described in detail via the four links below.
