BIO 181 Results Four procedures were conducted using the technique of spectrophotometry to identify solutes and their concentrations. For the ﬁrst procedure, a graph was constructed (see Fig. 1) plotting absorbance versus wavelength that represents the absorption spectrum for Cobalt Chloride (CoCl 2 ). The wavelength at the peak of absorbance was fou
