Hydrogen Peroxide Bubbling Reasons
On the cause of hydrogen peroxide bubbling
Hydrogen peroxide is often investigated by its bubbling image. The reason for this bubbling is not only one end, but also several.
First, catalysis. In case of manganese dioxide and other catalysts, the decomposition rate of hydrogen peroxide increases sharply. Catalysts can change the rate of chemical reactions, but their own mass and chemical properties remain unchanged before and after the reaction. Manganese dioxide can make the decomposition path of hydrogen peroxide easier, the activation energy is reduced, and the collision between molecules is more likely to initiate a reaction, so it quickly decomposes into water and oxygen, and the oxygen escapes. For example, in the experiment, when manganese dioxide is placed in a hydrogen peroxide solution, bubbles burst out instantly, which is a sign of catalyzing the reaction and causing a large amount of oxygen to be generated rapidly.
Second, due to heat. Hydrogen peroxide is thermally unstable. When heated, molecules gain energy, their movement intensifies, and the chemical bonds between molecules are more likely to break. When the temperature increases, the decomposition rate of hydrogen peroxide accelerates, decomposing into water and oxygen, and oxygen escapes from the solution, so bubbling is seen. If the hydrogen peroxide solution is heated slightly, bubbles can be seen gradually. The higher the temperature, the more bubbling. This is the reason why the decomposition is accelerated and the oxygen escape increases due to heat.
Third, the influence of impurities. If the hydrogen peroxide solution contains certain impurities, it may also cause its decomposition to bubble. Impurities may act as catalytic centers to induce the decomposition of hydrogen peroxide. And impurities and hydrogen peroxide sometimes chemically react, changing the reaction process, causing hydrogen peroxide to decompose into water and oxygen, and then generating bubbling phenomenon. If the solution contains trace metal ions, it may undergo redox reaction with hydrogen peroxide, causing hydrogen peroxide to decompose, and then bubbles appear.
From the perspective, hydrogen peroxide bubbles, or due to catalysis, heat, impurities and other factors, causing it to decompose and generate oxygen, and it is bubbling. This mechanism is of great significance in the research and practice of chemistry.
