Record the range of the melting range of your sample as
follows. In the Table record the temperature at which you
first see liquid beginning to form. The sample will
continue to melt. When the last of the sample has melted,
record the second temperature. These two values are
separated by a dash, i.e., 63-65 ° C. For a relatively pure
compound, this temperature range will generally be only a
few degrees.
