Hydrogen Peroxide Analysis
A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...
Beyond Benign
Exothermic and Endothermic Reactions
How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

Some A-level Reagents
Learning names and formulas can be a daunting task for young chemists, so support their study with interactive puzzles! First, users match each formula with its correct name. Then, individuals use them to complete three logic games.
Curated OER
Catalysts and Enzymes
Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Rate of Decomposition of Hydrogen Peroxide
Students devise an experiment to test the rate of decomposition of hydrogen peroxide. In this rate of reactions lesson plan, students use the given information in the lab to write a procedure that will allow them to find the rate of...
Curated OER
H2O2 Decomposition Lab II
Young scholars conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.
