Hydrogen Peroxide Steel Reaction
On the reaction between hydrogen peroxide and steel
Everything in the world changes endlessly, and the beauty of chemistry lies in the reaction. The reaction between hydrogen peroxide and steel is a corner of chemical exploration, but the mystery is also worthy of deep consideration.
Steel, a genus of iron-carbon alloys, is widely used and indispensable in many fields such as construction and equipment. Hydrogen peroxide, with the chemical formula\ (H_ {2} O_ {2}\), has strong oxidation and is widely used in chemical industry, medicine and other fields.
When hydrogen peroxide meets steel, its reaction is quite complicated. In steel, iron is the main component, iron atoms have variable valence states, and the strong oxidation of hydrogen peroxide can increase the valence of iron elements. At first, the oxygen atoms produced by the decomposition of hydrogen peroxide are very active and easy to contact with the iron surface. Iron atoms lose electrons and are oxidized to ferrous ions\ (Fe ^ {2 + }\)， Its chemical reaction formula can be expressed as:\ (Fe + H_ {2} O_ {2} + 2 H ^{ + } = Fe ^ {2 + } + 2H_ {2} O\).
However, ferrous ions are not stable. Under the continuous action of hydrogen peroxide, ferrous ions can be further oxidized to iron ions\ (Fe ^ {3 + }\) ， The reaction formula is as follows:\ (2Fe ^ {2 + } + H_ {2} O_ {2} + 2 H ^{ + } = 2Fe ^ {3 + } + 2H_ {2} O\).
This series of reactions continues on the surface of steel, causing gradual corrosion of the surface of steel. And the rate of the reaction is affected by many factors. When the temperature increases, the molecular thermal movement intensifies, the decomposition of hydrogen peroxide accelerates, and the reaction rate increases; the pH of the solution also plays a role, and the acidic environment is conducive to the reaction, because hydrogen ions can promote the decomposition of hydrogen peroxide and the oxidation of iron; and the impurity content and surface roughness of steel itself also affect the reaction. Impurities may become electrodes of primary batteries, accelerating corrosion; surface roughness increases the reaction contact area, making the reaction more rapid.
Looking at the reaction between hydrogen peroxide and steel, we can see the subtle chemical changes and the law of material interaction. In practical applications, it is necessary to clarify the reaction mechanism in order to find a way to protect steel, or to coat the surface of steel with a protective layer, or to adjust environmental factors to avoid excessive corrosion and maintain the performance of steel, so that it can serve human beings for a long time.
