'Record the absorbance value for 4ppm methyl group orange, making sure to zero the machine with the deionised weewee cuvette after all(prenominal) reading is taken.\r\nAfter I measured out my methyl orange I diluted each with deionised water up to the normalisation mark on the volumetric flask. 4. I accordingly poured each solution into separate cuvettes. 5. Recording the absorbance values for each always â€Å"zeroing” in between each reading with a cuvette containing deionised water. 6. Get the absorbance value of the unnamed solution. 7. Record results in Tables 8. Prepare a example curve graph 9.\r\nEstimate the concentration of the dark solution on your graph. Results Part Two slow-wittedness Discussion Using a colorimeter I used different coloured liquids to prove beer lamberts law. I did this experiment three beats each time recording my results. I believe I turn out beer lamberts law and this can be seen by my results which I have listed. I was also able to dress the concentration of an unknown solution by plotting it on my graph using its absorbance number.\r\n'
