Melting Point and Boiling Point

The purpose of this experiment was to observe the purity of a compound by testing its melting or boiling point. When a chemical is at a melting point, the vapor pressure of its solid phase is equal to that of the liquid phase. Impurities like H20 will lower the melting point of a compound. Reagents Tested: Cinnamic Acid Urea Pentane Analysis: Boiling Point of Pentane Pentane boils at about a third of the temperature of boiling water (see Table A […]

Simple and Fractional Distillation

The purpose of this experiment was to separate two liquids using Simple and Fractional Distillations. Separation by distillation works by manipulating the chemicals’ colligative properties and intermolecular forces. Reagents in the Experiment: Cyclohexane Toluene                                               Analysis: This experiment attempted to separate two liquids, cyclohexane and toluene. These chemicals have different intermolecular forces and therefore have dissimilar boiling points. […]
