For oxidation-reduction reactions in acidic conditions, after balancing the atoms and oxidation numbers, one will need to add H + ions to balance the hydrogen ions in the half reaction. For oxidation-reduction reactions in basic conditions, after balancing the atoms and oxidation numbers, first treat it as an acidic solution and then add OH − ...
Redox therapy is an experimental therapy [1] [2] that aims to effect an outcome by modifying the levels of pro-oxidant and antioxidant agents in cells. [3] The term "redox" is a contraction of "reduction-oxidation". For cancer patients, the therapy is predicated on the idea that the redox state of cells may have an effect on cancer development. [4]
This type of redox reaction is often discussed in terms of redox couples and electrode potentials. Atom transfer – An atom transfers from one substrate to another. For example, in the rusting of iron , the oxidation state of iron atoms increases as the iron converts to an oxide , and simultaneously, the oxidation state of oxygen decreases as ...
In the gas phase, the comproportionation reaction is much faster because of the much higher mobility of the reacting species as illustrated, e.g., in the Claus reaction where H 2 S and SO 2 react together to form elemental sulfur. Various classical comproportionation reactions are detailed in the series of examples here below.
In biochemistry, flavin adenine dinucleotide (FAD) is a redox-active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group, which may be in the form of FAD or flavin mononucleotide (FMN).
For example, adding more S (to the chemical reaction above) from the outside will cause an excess of products, and the system will try to counteract this by increasing the reverse reaction and pushing the equilibrium point backward (though the equilibrium constant will stay the same).
The Boudouard reaction, named after Octave Leopold Boudouard, is the redox reaction of a chemical equilibrium mixture of carbon monoxide and carbon dioxide at a given temperature. It is the disproportionation of carbon monoxide into carbon dioxide and graphite or its reverse: [ 1 ]
Reactions where the stereochemistry of the hydroxyl group is inverted saw lower regioselectivity, and removal of the hydroxyl group gave the exclusive formation of the other regioisomer. It is likely that the close proximity of the hydroxyl group in the syn isomer acidifies the ring-fusion proton through hydrogen-bonding interactions, thus ...
