a pure substance is a substance that only contains one compound or element throughout
a chemically pure substance will boil or melt at a specific temperature.
you can test the purity of a sample by measuring its melting/boiling point and comparing it to of a pure substance
impurities in your sample will:
-lower the melting point and increase the melting range of your substance
-increase the boiling point
