Colorimeter Essay Example for Free

Colorimeter EssayRecord the absorbance values for 4ppm Methyl orange tree, making sure to zero the motorcar with the deionised water cuvette after each reading 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. Recording the absorbance values for each always zeroing in mingled with each reading with a cuvette containing deionised water. 6. Get the absorbance value of the unknown solution. 7. Record results in T fittings 8. Prepare a standard curve graph 9.Estimate the concentration of the unknown solution on your graph. Results Part 2 Concentration Discussion Using a colorimeter I used different coloured liquids to try out beer lamberts law. I did this experiment three times each time recording 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 find the concentrat ion of an unknown solution by plotting it on my graph using its absorbance number.
