  2. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.

  3. Redox - Wikipedia

    en.wikipedia.org/wiki/Redox

    Electron transfer reactions are central to myriad processes and properties in soils, and redox potential, quantified as Eh (platinum electrode potential relative to the standard hydrogen electrode) or pe (analogous to pH as -log electron activity), is a master variable, along with pH, that controls and is governed by chemical reactions and ...

  4. List of unsolved problems in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Do replacement reactions of aryl diazonium salts (dediazotizations) predominantly undergo S N 1 or a radical mechanism? [6] Can an electrochemical cell reliably perform organic redox reactions? [7] Which "classic organic chemistry" reactions admit chiral catalysts?

  5. Electrochemical kinetics - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_kinetics

    Electrochemical kinetics is the field of electrochemistry that studies the rate of electrochemical processes. This includes the study of how process conditions, such as concentration and electric potential, influence the rate of oxidation and reduction reactions that occur at the surface of an electrode, as well as an investigation into electrochemical reaction mechanisms.

  6. Organic redox reaction - Wikipedia

    en.wikipedia.org/wiki/Organic_redox_reaction

    Organic redox reactions: the Birch reduction. Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds.In organic chemistry oxidations and reductions are different from ordinary redox reactions, because many reactions carry the name but do not actually involve electron transfer. [1]

  7. Disproportionation - Wikipedia

    en.wikipedia.org/wiki/Disproportionation

    In contrast, some authors use the term redistribution to refer to reactions of this type (in either direction) when only ligand exchange but no redox is involved and distinguish such processes from disproportionation and comproportionation. For example, the Schlenk equilibrium. 2 RMgX → R 2 Mg + MgX 2. is an example of a redistribution reaction.

  8. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    The decomposition of a reaction into half reactions is key to understanding a variety of chemical processes. For example, in the above reaction, it can be shown that this is a redox reaction in which Fe is oxidised, and Cl is reduced. Note the transfer of electrons from Fe to Cl.

  9. Electron transfer - Wikipedia

    en.wikipedia.org/wiki/Electron_transfer

    Example of a reduction–oxidation reaction between sodium and chlorine, with the OIL RIG mnemonic [1] Electron transfer (ET) occurs when an electron relocates from an atom, ion, or molecule, to another such chemical entity. ET describes the mechanism by which electrons are transferred in redox reactions. [2] Electrochemical processes are ET
