MgO2

Magnesium peroxide, with the chemical formula MgO2, is an inorganic compound. It is a white, crystalline solid that is sparingly soluble in water. Magnesium peroxide can be synthesized through various methods, often involving the reaction of magnesium salts with peroxides. One common method is the reaction of magnesium sulfate with hydrogen peroxide in the presence of a base.

MgO2 is known for its oxidizing properties. This characteristic makes it useful in certain applications. For instance, it has been explored for its potential in environmental remediation, particularly in the treatment of contaminated soils and groundwater. Its ability to release oxygen can help to enhance the biodegradation of organic pollutants by aerobic microorganisms. Additionally, magnesium peroxide has found applications in some pyrotechnic compositions and as a component in certain types of bleaching agents.

In terms of safety, magnesium peroxide is generally considered to be moderately hazardous. It can be an irritant to the skin, eyes, and respiratory tract. Like other peroxides, it can decompose exothermically, especially when heated or in contact with combustible materials, posing a fire hazard. Proper handling and storage procedures are therefore important when working with this compound. Its stability and reactivity are key considerations in its industrial and laboratory use.
