A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture. A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution ( NH 4 OH , or NH 3 (aq) ), and 30% hydrogen peroxide.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
The average toothbrush can be a breeding ground for germs, but with a little hydrogen peroxide you can disinfect them easily. Simply soak your bristles for a few minutes, and then rinse thoroughly ...
Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene).
VHP is produced from a solution of liquid H 2 O 2 and water, by generators specifically designed for the purpose. These generators initially dehumidify the ambient air, then produce VHP by passing aqueous hydrogen peroxide over a vaporizer, and circulate the vapor at a programmed concentration in the air, typically from 140 ppm to 1400 ppm, depending on the infectious agent to be cleared.

Here he is told that God gave the Garden of Eden to man "in earnest, or as a pledge of eternal life," but man was only able to dwell there for a short time because he soon fell from grace. In the poem, the Garden of Eden is both human and divine: while it is located on earth at the top of Mt. Purgatory, it also serves as the gateway to the heavens.
The most common use of organic peroxy acids is for the conversion of alkenes to epoxides, the Prilezhaev reaction. Formation of an epoxide from an alkene and a peroxycarboxylic acid. Another common reaction is conversion of cyclic ketones to the ring-expanded esters using peracids in a Baeyer-Villiger oxidation .
Lenses soaking in a hydrogen peroxide-based solution. The case is part of a one-step system and includes a catalytic disc to neutralise the peroxide over time. Hydrogen peroxide contact solutions are storage solutions for contact lenses that rely on hydrogen peroxide to clean the contacts and break up proteins and deposits during the ...
