Explain how this is accomplished in this experiment. What calculations do you need to perform? What measurements will 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 goal of this experiment was to learn how to prepare standard solutions from a stock solution and to use the standard solution to get a calibration curve to use to determine the concentration of an unknown solution.In part I. We had to obtain ferroin stock solution in a beaker. Rinse the curette several times with deionized water and then label them from 1-5. Using the digital pipettor and the 100 mL volumetric flask,
