Explain how this is accomplished in this experiment. What calculations do you need to perform? What measurements wil be made? [Do not provide experimental details here]. How do you go from calculated/measured values to accomplishing stated purpose? (10 pts: roughly divided 1 for the goal and 3 each for addressing each of the three parts of the experiment.)The purpose of this lab is to determine the amount of iron in an iron supplement tablet. We wil use absorbance spectroscopy to generate a calibration curve to determine the concentration of ferroin in the tablet solution. Five standard solutions of dif erent concentrations wil be prepared from a 6.25 x 10-4M stock solution of ferroin. A solution containing some of a crushed iron tablet ( tablet average weight = 436mg) and HCl, wil be heated then filtered.
