How is hydrogen peroxide formed?

Small, but detectable, amounts of hydrogen peroxide can be formed by several methods. Small amounts are formed by electrolysis of dilute acid around the cathode where hydrogen evolves if oxygen is bubbled around it. It is also produced by exposing water to ultraviolet rays from a mercury lamp, or an electric arc while confining it in a UV transparent vessel (e.g. quartz). It is detectable in ice water after burning a hydrogen gas stream aimed towards it and is also detectable on floating ice. Rapidly cooling humid air blown through an approximately 2,000 °C spark gap results in detectable amounts.

How does hydrogen peroxide differ from pure water?

In aqueous solutions, hydrogen peroxide differs from the pure substance due to the effects of hydrogen bonding between water and hydrogen peroxide molecules. Hydrogen peroxide and water form a eutectic mixture, exhibiting freezing-point depression down as low as –56 °C; pure water has a freezing point of 0 °C and pure hydrogen peroxide of −0.43 °C. The boiling point of the same mixtures is also depressed in relation with the mean of both boiling points (125.1 °C). It occurs at 114 °C. This boiling point is 14 °C greater than that of pure water and 36.2 °C less than that of pure hydrogen peroxide.

What is hydrogen peroxide?

Concentrated hydrogen peroxide, or " high-test peroxide ", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the O–O bond.

A brief history of hydrogen peroxide

Hydrogen peroxide was discovered in 1818 by French chemist Louis Jacques Thénard and was first used commercially to bleach hats. Hydrogen peroxide occurs naturally in very small amounts so industrial processes are used to make the 1 billion pounds of hydrogen peroxide needed annually, mostly for the bleaching of paper and pulp.

Why does hydrogen peroxide fizz?

Blood and most of our cells contain an enzyme called catalase. When hydrogen peroxide is poured on an open wound, the catalase instantly converts hydrogen peroxide into water and oxygen – these breakdown products generate the fizzing reaction we see on the skin. The fizzing does actually help remove and clear debris from the open wound.
