Word Equation. Zinc + Iodine = Zinc Iodide. Zn + I = ZnI2 is a Synthesis reaction where one mole of Zinc [Zn] and two moles of Iodine [I] combine to form one mole of Zinc Iodide [ZnI 2]
This experiment involves the synthesis of a metal salt by direct reaction of a metal and a non-metal. Zinc powder is added to a solution of iodine in ethanol. An exothermic redox reaction occurs, forming zinc iodide, which can be obtained by evaporating the solvent. Zn + I 2 → ZnI 2
18 Αυγ 2020 · This video demonstrates the reaction of equal parts of zinc and iodine to create zinc iodide.
Determination of a chemical formula: the synthesis of zinc iodide. OBJECTIVES: In this experiment zinc iodide will be prepared from its elemental components. The results will be analyzed to evaluate the composition and to determine the empirical formula of the compound. SKILLS: weighing, stoichiometric calculations.
In this experiment, zinc iodide will be synthesized by combining granular zinc metal with elemental iodine dissolved in a slightly acidic aqueous solution. The masses of iodine and zinc that react will be measured, from which the mole ratio, mol I/mol Zn, can be calculated and the empirical formula, ZnxIy determined.
Results and Discussion - Experiment 2 - Empirical Formulas A. Synthesis and formula of zinc iodide, 1. Write the expected balanced equation for the reaction between zinc and iodine 2. Mass of beaker 29.52 g 3.
15 Φεβ 2018 · Zinc and iodine, when mixed with distilled water in a test tube, will react spontaneously and exothermically to produce aqueous zinc iodide. The aqueous zinc iodide can be decomposed into its elements using a simple electrolysis apparatus.
