Lab 5: OCHEM 1 | QUE & ANSW Liquid-Liquid extraction **** mixtures that contain different solubility properties that are separated by the "partitioning" of 2 immiscible phases -typically H20 and an organic solvent. Can mixtures with similar solubility properties be separated? ****

Lab 2: OCHEM 1 Melting point of a solid compound **** temperature at which a phase transition from solid to liquid occurs Melting point of a pure crystalline compound ****

Lab 6: OCHEM 1 |Reviewed Questions and Answers In this experiment, what are we isolating? **** (S) - 1 phenylethylamine How are we going to isolate it? **** Racemic (1) phenylethylamine will be reacted with enatiomerically pure (2R,3R) tartaric acid to form diastereoisomeric salts which can be resolved by selective crystallation from methanol
