Methods for separating mixtures

Methods for separating mixtures

1. Homogeneus mixures

   • Methods to separate
     • Distillation
       • Distillation is an effective method to separate mixtures comprised of two or more pure liquids.
     • Chromatography
       • Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates
     • Evaporation
       • Evaporation is a technique used to separate out homogeneous mixtures where there is one or more dissolved salts.

2. Heterogeneus mixture

   • Methods to separe
     • Filtration
       • Filtration is a separation method used to separate out pure substances in mixtures comprised of particles, some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture
     • Sifting
       • It consists of separating a mixture of solid materials of different sizes, for example grains of corn and sand using a sieve (strainer)
     • Decantation
       • It is used to separate two liquids with different densities or a mixture consisting of a solid insoluble in a liquid
