Lab Report 2: Mixed Melting Points The purpose of the experiment is to determine compounds by studying their melting point ranges and to create a melting-point composition diagram. Two melting-point capillaries were used to melt small amounts of a given unknown compound. The starting temperature on the Mel-Temp 3.0 was set about ten degrees lower than that of the lowest melting point possible from the list of compounds that were researched in the pre-lab. The end temperature was set five degrees above the highest melting point temperature. The first capillary was used only to narrow the melting point range down for the purposes of saving time. The contents of the second capillary were heated at a more gradual rate to carefully observe and accurately record the melting point range. Once this range is discovered, it is recorded on the board in a chart. The chart is then used to find a melting point range close to if not the same as one’s observed range to identify like compounds.
