Cost Production and Percent Yield of Zinc Iodide Introduction Zinc was reacted with iodine with the help of the catalyst acetic acid in order to determine the appropriate cost of production of zinc iodide for a chemical plant. The effectiveness of the procedures was assessed by calculating percent yield. The cost of production wad determined by reacting zinc with iodine in acetic acid and determining the limiting reagent, excess reagent, and percent yield. From this data, the cost of production for 1000 kg of zinc iodide could be determined. Experimental Procedure On an analytical balance, 0.5g iodine and 0.5g zinc were weighed out and placed in test tube #1. Three boiling chips were placed into test tube #2, and the mass of the tube and contents were weighed. Approximately 1 mL of 0.20M acetic acid was placed into test tube #1 with the reactants. The mixture was continually agitated until the reaction went though two significant color changes over a period of five minutes. After the reaction was finished, 1 mL portions of the dilute acid were used to rinse the solid and decant the rinse into test tube #2
