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 ie components of a mixture retain their individual chemical properties, this can be important when considering formulations. Components of a mixture can be separated by physical means and these methods are described in detail via the links below.

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