Colorimeter Essay

Record the absorbance values for 4ppm Methyl orange, qualification sure to zero the machine with the deionised water cuvette after each exercise is taken.After I measured out my methyl orange I diluted each with deionised water up to the calibration mark on the volumetric flask. 4. I then poured each solution into separate cuvettes. 5. put down the absorbance values for each always zeroing in between each nurture with a cuvette containing deionised water. 6. Get the absorbance value of the chartless solution. 7. Record results in Tables 8. raise a standard curve graph 9.Estimate the concentration of the unknown solution on your graph. Results Part Two Concentration Discussion employ a colorimeter I used different coloured liquids to corroborate beer lamberts law. I did this experiment three times each time put down my results. I believe I proved beer lamberts law and this can be seen by my results which I have listed. I was also able to control the concentration of an unkno wn solution by plotting it on my graph victimization its absorbance number.
