A chemical solution exhibits several properties: A solution consists of a homogeneous mixture. A solution is composed of one phase (e.g., solid, liquid, gas) Acetone is commonly used as a solvent to manufacture plastics and other industrial products. Acetone may also be used to a limited extent in household products, including cosmetics and personal care products, where its most frequent application would be in the formulation of nail polish removers Recrystallization is the most important method of purifying nonvolatile organic solids.Recrystallization involves dissolving the material to be purified (the solute) in an appropriate hot solvent.As the solvent cools, the solution becomes saturated with the solute and the solute crystallizes out (reforms a solid) For example, the most appropriate liquid may not have suitable physical properties for direct use as solvent. In such cases it can be used dissolved in another suitable liquid. The active component of the mixture is then known as the extractant and the liquid in which it is dissolved as the diluent. The solvent comprises the two together
