In the lab report example below, we have mentioned the chemical reaction that takes place with manganese dioxide (MnO2) to break down hydrogen peroxide (H2O2) into water (H2O) and Oxygen (O2). As the lab report illustrates, Manganese dioxide is an inorganic catalyst and can speed up a reaction. As the Pre-Lab & Question segment illustrates, H2O2 will break down naturally in the presence of light, and that is why it is advised to keep it in the dark brown bottle. Nevertheless, when MnO2 is added to H2O2, the reaction rate dramatically increases. The enzyme lab report here also breaks down important points for the Background segment, the purpose of the lab report segment, and the procedure that you have to follow in your laboratory to achieve the said result.
