    • Dialysis
      Dialysis is the separation of colloids from dissolved ions or molecules of small dimensions, or crystalloid, in a solution.  Dialysis is a process that is like osmosis. Osmosis is the process in which there is a diffusion of a solvent through a semipermeable membrane.
    • Recrystallization
      Recrystallization, also known as fractional crystallization, is a procedure for purifying an impure compound in a solvent. The method of purification is based on the principle that the solubility of most solids increases with increased temperature. This means that as temperature increases, the amount of solute that can be dissolved in a solvent increases.
