Piranha solution, also known as piranha etch, is a mixture of sulfuric acid ( H2SO4) and hydrogen peroxide ( H2O2 ). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [1] Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most ...
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).
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.
In the wash, both compounds dissolve in the water. When dissolved in water, the persalt releases hydrogen peroxide (e.g. from sodium percarbonate): 2Na 2 CO 3 ∙3H 2 O 2 → 2Na 2 CO 3 + 3H 2 O 2. In a basic wash solution, hydrogen peroxide loses a proton and is converted to the perhydroxyl anion: H 2 O 2 ⇌ H + + HO 2 −
Hydrogen peroxide itself (H 2 O 2). It is used, for example, to bleach wood pulp and hair or to prepare other bleaching agents like the perborates, percarbonates, peracids, etc. Sodium percarbonate (Na 2 H 3 CO 6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3).
Haber-Weiss chain reaction. The main finding of Haber and Weiss was that hydrogen peroxide (H 2 O 2) is decomposed by a chain reaction. [2] The Haber–Weiss reaction chain proceeds by successive steps: (i) initiation, (ii) propagation and (iii) termination. The chain is initiated by the Fenton reaction: Then, the reaction chain propagates by ...
When asked about Oil and Vinegar Howard Deutch said, Yes. That was John's favorite script and he was saving it for himself, and I convinced him to let me do it. It was the story of a traveling salesman that Matthew Broderick was going to play, and a rock-and-roll girl, a real rocker. Polar opposites. Molly [Ringwald] was going to play that.
The physiological importance of peroxiredoxins is indicated by their relative abundance (one of the most abundant proteins in erythrocytes after hemoglobin is peroxiredoxin 2). Their function is the reduction of peroxides, specifically hydrogen peroxide, alkyl hydroperoxides, and peroxynitrite.
