Oxygen and methylene blue
Reacting hydrogen peroxide, and potassium manganate together will produce detectable oxygen so by using methylene blue solution, and a gas generating apparatus students can test for the presence of oxygen in this practical. Includes kit list and safety instruction.
Using methylene blue solution, students will test for the presence of O2 created during the reaction of hydrogen peroxide and potassium manganate (VII), in their own gas generating apparatus.
