What are peroxides in chemistry?
What are peroxides in chemistry?
Peroxide, any of a class of chemical compounds in which two oxygen atoms are linked together by a single covalent bond. Several organic and inorganic peroxides are useful as bleaching agents, as initiators of polymerization reactions, and in the preparation of hydrogen peroxide (q.v.) and other oxygen compounds.
Is O2 a peroxide?
The O−O group in a peroxide is called the peroxide group or peroxo group. The nomenclature is somewhat variable. The most common peroxide is hydrogen peroxide (H2O2), colloquially known simply as “peroxide”….Peroxide.

Which elements are peroxides?
Hydrogen peroxide is a highly reactive chemical containing the elements hydrogen and oxygen.
Why is H2O2 called peroxide?
Hydrogen peroxide, on the other hand, as is evident from the structure in figure 2 below, contains not two O2− units but a single O22− unit, composed of two oxygens bound to each other. This means that oxygen’s oxidation state is −I rather than −II and that hydrogen peroxide is readily reduced.
What is superoxide example?
Sodium superoxide (NaO2) can be prepared with high oxygen pressures, whereas the superoxides of rubidium, potassium, and cesium can be prepared directly by combustion in air. By contrast, no superoxides have been isolated in pure form in the case of lithium or the alkaline-earth metals, although…
What is peroxygen?
A peroxygen is a chemical containing a peroxide anion or an O-O single bond group, most often found in sanitizing formulations in the hydroperoxide form (-OOH). Peroxides are part of a larger oxides chemical family that also contains superoxide, ozone (O3), and ozone’s UV catalysis product, hydroxide radical anion.

What is Superperoxide?
A superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. . The systematic name of the anion is dioxide(1−). The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O2, which occurs widely in nature.
What is a formula that represents a peroxide?
The formula for the peroxide ion is O22-. Hydrogen peroxide, commonly found in medicine cabinets and referred to as “peroxide”, has the formula H2O2.
Does hydrogen peroxide and peroxide the same thing?
The key difference between peroxide and hydrogen peroxide is that peroxide is an anion whereas hydrogen peroxide is a chemical compound . Peroxides are a special category of oxygen compounds with unique properties. Hydrogen peroxide was discovered by the French scientist Thenard in 1818.
Is hydrogen peroxide the miracle cure?
According to some people, hydrogen peroxide also has amazing acne-fighting capabilities. Unfortunately, it may not be the miracle cure you’ve been searching for. The theory behind using hydrogen peroxide as an acne treatment is that it supposedly kills bacteria on your skin and helps to dry up sebum. Hydrogen peroxide is an oxidizing agent.
What household items contain hydrogen peroxide?
Hydrogen peroxide is used as an antimicrobial agent, an oxidizing and reducing agent, and bleaching agent in foods such as milk and cheese products, wine, vinegar, starch and instant tea.
