Product Details

College Level General Chemistry Guided-Inquiry Experiment Does the concentration of hydrogen peroxide deteriorate as it ages? In this guided-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.
