Beer's Law: Colorimetry of Copper(II) Solutions

2008-8-29  Copper (II) nitrate appears blue to the eye. This is because red light is absorbed and blue light is transmitted (Table 1). The amount of red light absorbed is directly proportional to the concentration of the copper (II) ions in the solution as defined by Beer's Law. In this experiment we will measure the absorbance of several copper
