Lab Report Example erstwhile the cuvette is filled and locked. Place it in the touchimeter and read the first wavelength. This lead be your base interlingual rendition that you use to determine the intensity of color in the upcoming readings. Once that is read, you can then bully the cuvette again. You will get a reading for each setting on the Calorimeter (430nm, 470nm, 565nm,635nm). You will use the last-place percentage reading and stick with that setting for the duration of the experiment.You will then start using your color solution to get readings and determine the intensity of color. You will begin doing this by adding more dye to the solution. You will start at 10% and work your way up to 100% .Each time you add a percentage of water to the solution you will place the cuvette into the calorimeter and read the results. Each time you finish acquire the results, clean the cuvette and begin to do it again to all other percentages.The graph gives the best fit line, or the str aightest line is one that predicts vs niggardliness. This graph however, does not match the equation of Beer-Lamberts law. The x-axis of the Beer-Lamberts equation represents the concentration while the y-axis represents the absorbance. Lambert-Beer Law is used to determine concentration M, mM, ormM from Absorbance No unit, if the molar extinction coefficienteM-1cm-1 of a compound and the path length of the cuvette cm that the distance light passes through the solution are known.The formulaof this affinityThe possible limitations of spectroscopy used in this investigation are the narrowness of spectra and effect of stray radiations that superpower have made the measurements of absorbance upon slit width and wavelength setting and the fact that it is not possible to know molecular weight of substance could also affect the investigation.The goal of this experiment is to find the factors that affect the intensity of color. This was make
