Melting point is the technique that disrupts the IMAF’s and forces the molecule to break by adding thermal energy to increase kinetic energy to the compound. When melting the unknown the interactions within the IMAF’s of the molecule are decreasing causing a disruption within the structure of the lattices. Determining the melting point of Unknown 105 A helps narrow down the possible compound that it can be, by the given melting point range. The narrower the range represents the relative purity of the substance.
Simple distillation is the technique that disrupts the IMAF’s and forces the molecules to break by adding thermal energy to increase the kinetic energy for the molecule to overcome their IMAF’s so that the molecule is able to leave and go into gas phase. This happens when the vapor pressure is equal to the atmospheric pressure. Doing this test will give a pure liquid of Unknown 105 B. …show more content…
When running a recrystallization test adding the solid into the solvent at room temperature should show that the interactions of the solute and solvent IMAF’s are weak because the solid did not dissolve in the solvent. But by adding thermal energy in the form of heat increased the kinetic energy weakening the IMAF’s between the solutes forcing the molecule to dissolve in the solvent. By increasing interactions between solvent and solute, also changing the lattice structure of the molecule. Then when cooling the heated solution, the IMAF’s become stronger between the solute and solute recreates the lattice structure of the solid that was presented before heating but without impurities. The crystal structure will only allow the structures that fit, and segregate the ones that don’t; which in return help remove any impurities that were present in the
