  2. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    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 − ...

  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. Boudouard reaction - Wikipedia

    en.wikipedia.org/wiki/Boudouard_reaction

    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 ]

  5. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    The increase in the oxidation state of an atom, through a chemical reaction, is known as oxidation; a decrease in oxidation state is known as a reduction. Such reactions involve the formal transfer of electrons: a net gain in electrons being a reduction, and a net loss of electrons being oxidation. For pure elements, the oxidation state is zero.

  6. Mercury beating heart - Wikipedia

    en.wikipedia.org/wiki/Mercury_beating_heart

    The mercury beating heart is an electrochemical redox reaction between the elements mercury, iron and chromium. The reaction causes a blob of mercury in water to oscillate. The observeable reaction demonstrates an effect of a non-homogeneous electrical double layer. [1] [2] It is often used as a classroom demonstration.

  7. Substitution reaction - Wikipedia

    en.wikipedia.org/wiki/Substitution_reaction

    The two reactions are named according tho their rate law, with S N 1 having a first-order rate law, and S N 2 having a second-order. [2] S N 1 reaction mechanism occurring through two steps. The S N 1 mechanism has two steps. In the first step, the leaving group departs, forming a carbocation (C +). In the second step, the nucleophilic reagent ...

  8. Benzilic acid rearrangement - Wikipedia

    en.wikipedia.org/wiki/Benzilic_acid_rearrangement

    First performed by Justus von Liebig in 1838, [1] it is the first reported example of a rearrangement reaction. [2] It has become a classic reaction in organic synthesis and has been reviewed many times before. [3] [4] [5] It can be viewed as an intramolecular redox reaction, as one carbon center is oxidized while the other is reduced. Scheme 1.

  9. Cannizzaro reaction - Wikipedia

    en.wikipedia.org/wiki/Cannizzaro_reaction

    The Cannizzaro reaction, named after its discoverer Stanislao Cannizzaro, is a chemical reaction which involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to give a primary alcohol and a carboxylic acid.
