Analysis of Zinc Tablets: An Extension to a Stoichiometry Experiment

Using a titration, students can determine the stoichiometry of the reaction between zinc ion and ferrocyanide ion. The technique can then be used to determine the concentration of zinc ion or ferrocyanide in unknown solutions or the amount of zinc ion in commercially available tablets. The experimen...

Description
Summary:Using a titration, students can determine the stoichiometry of the reaction between zinc ion and ferrocyanide ion. The technique can then be used to determine the concentration of zinc ion or ferrocyanide in unknown solutions or the amount of zinc ion in commercially available tablets. The experiment teaches many important general chemistry laboratory techniques, such as preparation of standard solutions and quantitative use of pipets and burets. The application of solution stoichiometry calculations provides an important link between lecture and the laboratory.
