Percentage of H₂O₂ in Your Drugstore Hydrogen Peroxide
This lab is an introduction to Redox titration. Students use a redox probe and titration to determine the hydrogen peroxide content of a drugstore formulation.
Students will be expected to apply knowledge of balancing reduction-oxidation reactions and half reactions in order to complete this lab. They standardize a solution of potassium permanganate using ferrous ammonium sulfate, then use the permanganate to titrate against a diluted sample of drugstore 3% hydrogen peroxide.Preview Download

This probe connects to a Wireless pH Sensor and allows students to determine the ability of a species in a solution to act as an oxidizing agent or reducing agent.
This compact hot plate and stirrer is an essential for any chemistry lab!
Use the new Wireless Drop Counter for more efficient and accurate titration data. Conducting a titration has never been easier!
Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.
Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
