The goal of the experiment was to determine the unknown concentration of the provided Cobalt (II) solution by using a spectrophotometer/colorimeter. The spectrophotometer was used on the unknown solution to find the concentration of Cobalt (II). The concepts used from Beer-Lambert’s Law are the absorbance and concentration of the tested solution. The equation is A=EbC. A equals absorbance, E is the constant when identifying the species measuring the wavelength, b is the thickness of the solution
