Product Details

Big Idea 3, Investigation 8, Primary Learning Objective 3.9. Old bottles of hydrogen peroxide that are past their expiration dates are often found in medicine cabinets and chemical stockroom shelves. Does the concentration of hydrogen peroxide deteriorate as it ages? In this advanced inquiry lab, students design an experiment to determine the percent composition of a common "drug store" bottle of hydrogen peroxide using an oxidation-reduction titration. Students begin by standardizing a solution of potassium permanganate using ferrous ammonium sulfate. This procedure provides a model for a guided-inquiry activity, during which students design a titration experiment to determine the precise concentration of hydrogen peroxide in solution. Additional samples of hydrogen peroxide may be used to allow opportunities for further open-inquiry experiments. Fulfill key learning objectives relating to quantitative analysis, stoichiometry calculations, and balancing redox reactions with this great real-world application that also develops science practice skills for collecting and analyzing data and refining measurements. Complete for 24 students working in pairs. Additional samples of hydrogen peroxide are available separately. Common laboratory equipment is required and available separately.
