PPT-Experiment 2 RECRYSTALLIZATION

Solid organic compounds when isolated from organic reactions are usually impure they are usually contaminated with small amounts of other compounds that are produced along with the desired compound The purification of impure crystalline compounds is usually done by recrystallization from a suitable solvent or a mixture of solvents.
