the concentration of Cu(II) ions was determined and ultimately the mass percentage of copper. 2 Solutions needed for this experiment: Solutions prepared by the student Solutions provided by the instructorrelationship is best determined using a wavelength of light in a region of the visible spectrum where the maximum absorbance is observed. This wavelength is known as λ max and is most sensitive to the changes in concentration. The purpose of this experiment was to study the absorbance of CuSO 4. Because copper compoundsthe 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 (II) solutions. Table 1. Correlation between wavelength,
