FlinnPREP™ Inquiry Labs for AP® Chemistry: Analysis of Hydrogen Peroxide
By: The Flinn Staff
Item #: AP7647
In the Analysis of Hydrogen Peroxide Inquiry Lab Solution for AP® Chemistry, students use an oxidation-reduction titration to determine the percent composition of hydrogen peroxide, while learning about concepts relating to quantitative analysis and more.
Includes access to exclusive FlinnPREP™ digital content to combine the benefits of classroom, laboratory and digital learning. Each blended learning lab solution includes prelab videos about concepts, techniques and procedures, summary videos that relate the experiment to the AP® exam, built-in student lab safety training with assessments, and standards-based, tested inquiry labs with real sample data. FlinnPREP™ Inquiry Lab Solutions are adaptable to you and how you teach with multiple ways to access and run your AP® labs.
Big Idea 3, Investigation 8, Primary Learning Objective 3.9
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. 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. Refill kit includes chemicals and consumable supplies.
