Colorimeter Essay

picture the absorbance values for 4ppm Methyl orange, qualification sure to zero the machine with the deionised water cuvette after from each one reading is taken.After I heedful out my methyl orange I diluted each with deionised water up to the calibration congeal on the volumetric flask. 4. I then poured each upshot into separate cuvettes. 5. Recording the absorbance values for each always zeroing in between each reading with a cuvette containing deionised water. 6. Get the absorbance value of the unknown solution. 7. Record results in Tables 8. Prepare a standard curve interpret 9.Estimate the concentration of the unknown solution on your graph. Results Part Two Concentration Discussion Using a colorimeter I apply different coloured liquids to prove beer lamberts law. I did this experiment three times each time arranging my results. I believe I proved beer lamberts law and this can be seen by my results which I agree listed. I was also able to find the concentration of a n unknown solution by plotting it on my graph using its absorbance number.
