Hydrogen Peroxide Metal Reaction
On the Reaction of Hydrogen Peroxide with Metals
Hydrogen peroxide is active and often shows the ability to oxidize. Metals have a wide variety of categories and different properties. When the two meet, the reaction is particularly impressive.
In common metals, the reaction of iron and hydrogen peroxide is very interesting. Iron has the property of changing price. When encountering hydrogen peroxide, if the environment is acidic, ferrous ions can be oxidized into iron ions by hydrogen peroxide. During the process, the valence state of oxygen in hydrogen peroxide changes from -1 to -2, indicating its oxidizing properties, while ferrous ions lose electrons and rise to iron ions. The rate of this reaction is affected by factors such as pH and temperature of the solution. When the temperature increases, the reaction rate is accelerated; the acidity is enhanced, which also helps the reaction to proceed.
Another example is the reaction between zinc and hydrogen peroxide. Zinc is more active and meets hydrogen peroxide, which can promote the decomposition of hydrogen peroxide. In this reaction, zinc either acts as a catalyst for the decomposition of hydrogen peroxide, or participates in the reaction itself. If there are impurities in zinc, the reaction situation is more complicated. Impurities can form a tiny primary battery with zinc, accelerating the reaction process. Hydrogen peroxide decomposes to form water and oxygen. During this process, bubbles may escape from the surface of zinc, which is due to the formation of oxygen.
Look at the reaction between copper and hydrogen peroxide again. Under normal conditions, the reaction is not obvious. However, if there is a suitable catalyst, or if the reaction environment is changed, such as increasing the temperature and adjusting the pH, the reaction can also occur. Copper can be oxidized by hydrogen peroxide to form copper oxides or copper ions, and hydrogen peroxide is reduced.
In summary, the reaction between hydrogen peroxide and metals varies depending on the type of metal and the reaction environment. Or the metal is oxidized, or the hydrogen peroxide is decomposed. The wonders of chemical changes need to be explored in depth by our generation, so as to make sense and use it in practice for the benefit of people.
