The rationalization method can be broken down into seven steps: 1) Choosing the solvent, 2) Dissolving the solute, 3) Decontrolling the Solution, 4) Filtering suspended solids, 5) Rationalizing the solute, 6) Collecting and washing the crystals, and 7) Drying the product. Activated Charcoal is used in Rationalization to absorb the impurities that are in the solution.

Phthalate Acid melted just ICC less than the standard melting point for Phthalate Acid. Naphthalene melted ICC less and Benzene Acid also did not reach the standard melting point. Reasons for a low percent Recovery for Phthalate Acid and Naphthalene is probably because not all to the solid were collected when filtered out. Reasons tort Benzene Acid being over 1 00 % is probably because there was an excess of and it was not filtered out correctly. Conclusion To conclude, the experiment was successful in creating crystals and removing hem from impurities.
