The mass percentage of copper in brass can be determined by first reacting it with concentrated nitric acid, and then using a colorimeter to analyze the color intensity of the copper(II) nitrate solution that forms. Copper reacts readily with oxidizing agents. In this experiment, concentrated nitric acid oxidizes copper metal to the copper(II) ion.
