WebA student prepared five solutions of CuSO 4 with different concentrations, and then filled five cuvettes, each containing one of the solutions. The cuvettes were placed in a spectrophotometer set to the appropriate wavelength for maximum absorbance. The absorbance of each solution was measured and recorded. WebTo do this you will use the spectrophotometer to select a wavelength of light and measure and record the absorbance of the sample at that wavelength. Use the labeled picture …
