Separation Techniques
Mixtures are made up of two or more two substances. Some mixtures are water-soluble while some of them are not. For example, the salt solution is a water-soluble mixture whereas a mixture of sand and iron nails is a water-insoluble mixture. The iron nails and sand mixture can be easily separated using magnetic separation methods.
separation and purification
Separation methods, then, can be defined as processes that change the relative amounts of substances in a mixture.
