Description

In experiment C1.2.2.1, the law of definite proportions is confirmed by the synthesis of magnesium oxide. Magnesium reacts with oxygen in a luminous reaction to magnesium oxide.

The starting material magnesium and the product magnesium oxide can be weighed. In addition, the quantity of oxygen consumed is determined by measuring the volume. The results can be used to determine the mass ratio of oxygen to magnesium. Repeated tests can then show that it remains constant.
