Synthesis of Zinc Iodide Jessica Edwards Chem 104 Section 30 Performed: 9/4/2007 Submitted: 9/11/2007 Abstract: The objective of the experiment was to determine the formula of zinc iodide and properly figure out the percent yield of zinc and iodine. From the data, it is possible to calculate the masses of zinc and iodine reacted as well as the mass of zinc iodide produced. To find the empirical formula, Zinc metal with elemental Iodine will need to be reacted to create the compound of Zinc Iodide.
