WebbMelting Point and Freezing Point. Pure, crystalline solids have a characteristic melting point, the temperature at which the solid melts to become a liquid.The transition between the solid and the liquid is so sharp for small samples of a pure substance that melting points can be measured to 0.1 o C. The melting point of solid oxygen, for example, is … WebbExperiment 1: Coupling between 2-naphthol and 4-aminobenzenesulfonic acid Procedure 1. In test tube A, add approximately 0.5 mL of conc.
