A few common chemicals supplied by the druggist and simple apparatus is all that is required to produce these interesting experiments with oxygen. by VERNON TRACEY OXYGEN experiments form a very interesting field of adventure for the amateur chemist due to the fact that oxygen is one of the most active of the chemical elements. It readily combines with most any other element to form many different compounds. These compounds of oxygen and other elements are known as "oxides" and the process of combination is called "oxidation," or more commonly known as burning. We see examples of oxidation every day in the burning of fuel, but this is not very active when one considers the fact that the air is only one-fifth oxygen, the rest being mainly nitrogen and a small percentage of other gases.
