Description

Experiment C1.2.3.1 determines the mass ratios of copper and oxygen in copper(I) oxide and copper(II) oxide. In these compounds, the elements copper and oxygen are combined with one another in different mass ratios. Those different ratios can be determined by quantitative reduction with hydrogen.
