C HEMISTRY 11L R EPORT T EMPLATE EXPT. Beer’s Law 8 Introduction The parsley will have the highest iron concentration of mg of iron per 100 g food. Unlike parsley, the fruits have a large amount of water and sugars in them, making them have a lower iron concentration. Instead parsley has a lot of minerals which will mean it has a higher concentration of iron. The purpose of this experiment is to use pyrolysis, Beer’s Law, and colorimetry to determine the iron content in different food samples. The purpose of this lab report is to compare values determined experimentally with classmates and USDA values to determine which food sample has the highest iron content. Materials and Methods The procedure for this experiment was taken from the Chemistry 101 Lab Manual. There were no deviations from the given procedure. Results and Discussion Pyrolysis is breaking apart a food sample with fire until it is grey ash. Dried parsley was pyrolyzed in this experiment. The mass of the empty crucible is determined of both sample 1 and sample 2; these values are 17.602 g and 18.559 g respectively. The parsley was put into the crucible, and then the mass of the crucible and food was determined. For sample 1 the mass of the crucible and food is 17.795 g, and for sample to, 18.745 g. The mass of the parsley was determined by subtracting the mass of the empty crucible from the mass of the crucible and food. The mass of food for sample 1 is 0.193 g, and for sample
