Solutions

Expert Solution

Processes are often classified according to the particular differences they use to achieve separation

Recrystallization

  • By dissolving both impurities and a compound in an appropriate solvent, either the desired compound or impurities can be removed from the solution, leaving the other behind

Electrophoresis

  • is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field
  • Electrophoresis of positively charged particles (cations) is sometimes called cataphoresis, while electrophoresis of negatively charged particles (anions) is sometimes called anaphoresis.

Evaporation

  • When a molecule near the surface absorbs enough energy to overcome the vapour pressure, it will escape and enter the surrounding air as a gas. When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling.

Chromatography

  • It is a technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. Following are the types of Chromatography:
  • High-performance liquid chromatography (HPLC)
  • Thin-layer chromatography (TLC)
  • Countercurrent chromatography (CCC)
  • Droplet countercurrent chromatography (DCC)
  • Paper chromatography
  • Ion chromatography
  • Size-exclusion chromatography
  • Affinity chromatography
  • Centrifugal partition chromatography
  • Gas chromatography and Inverse gas chromatography
