When dissolving copper in nitric acid, copper(II) ions produce a blue-colored solution. It is possible to determine the concentration of copper(II) ions, focusing on the hue of the color, using a smartphone camera. A free app can be used to measure the hue of the solution, and with the help of standard copper(II) solutions, one can graph a calibration curve to determine the concentration of copper in solution and calculate the mass of copper that has been dissolved or, for example, the percentage of copper in an alloy.
