When hydrogen peroxide bubbles, it is undergoing a chemical change. Which statement best describes what is happening? The atoms in hydrogen peroxide are breaking apart and forming new types of molecules. Four students are analyzing four different substances and recording their findings in this table.
Hydrogen peroxide spontaneously decomposes into water and oxygen. The equation for the reaction is. #2H_2O_2 â 2H_2O + O_2#. The rate of decomposition is slow at room temperature, but it increases with temperature. The rate increases rapidly in the presence of catalysts such as #MnO_2# and #KI#. Hydrogen peroxide is a powerful oxidizing agent. At low concentrations (3 %), it is used as a disinfectant and a bleach. The UV light from the sun catalyzes the reaction.
