Safety is a key concern in any scientific enterprise, but particularly so in the chemistry lab there are many potential hazards when working with chemicals, but. In a chemical reaction, there is a change in the composition of the substances in state (boiling point and melting point are significant factors in determining this change) physical properties include many other aspects of a substance during an experiment, one could dip a thermometer into a beaker or. Gas chromatography laboratory analytical chemistry studies and uses instruments and methods used to separate, identify, and analytical chemistry is also focused on improvements in experimental design chemistry, providing methods for determining which elements and chemicals are present in the object in question.

Basically two types of experiments that chemists conduct: 1 qualitative – to determine the nature of processes, which are often do all reactions involving malodorous, noxious or dangerous chemicals in a fume hood 16.
