This lab replaces manganese dioxide to demonstrate the effect of a catalyst in a reaction. Students will understand the effect of a catalyst on reaction rates and how a catalyst can improve the efficiency of a process.
Reaction Rates & Equilibrium
A Presidential Green Chemistry Award winning technology is the inspiration for this lab that looks chemically at the difference between hard and soft water and the role of catalysis in reactions. The lesson reinforces the scientific method by careful manipulation of variables to develop a rich understanding of the bleaching process through an inquiry based activity.
