  2. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...

  3. Redox gradient - Wikipedia

    en.wikipedia.org/wiki/Redox_gradient

    A redox gradient is a series of reduction-oxidation (redox) reactions sorted according to redox potential. [ 4 ][ 5 ] The redox ladder displays the order in which redox reactions occur based on the free energy gained from redox pairs. [ 4 ][ 5 ][ 6 ] These redox gradients form both spatially and temporally as a result of differences in ...

  4. Reduction potential - Wikipedia

    en.wikipedia.org/wiki/Reduction_potential

    In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential ...

  5. Redox - Wikipedia

    en.wikipedia.org/wiki/Redox

    Redox (/ ˈrɛdɒks / RED-oks, / ˈriːdɒks / REE-doks, reduction–oxidation[2] or oxidation–reduction[3]: 150 ) is a type of chemical reaction in which the oxidation states of the reactants change. [4] Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the ...

  6. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    Half-reaction. In chemistry, a half reaction (or half-cell reaction) is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Often, the concept of half reactions is used to describe what occurs ...

  7. Standard hydrogen electrode - Wikipedia

    en.wikipedia.org/wiki/Standard_hydrogen_electrode

    Standard hydrogen electrode. In electrochemistry, the standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be 4.44 ± 0.02 V[ 1 ] at 25 °C, but to form a basis for comparison with all other ...

  8. Redox indicator - Wikipedia

    en.wikipedia.org/wiki/Redox_indicator

    A redox indicator (also called an oxidation-reduction indicator) is an indicator which undergoes a definite color change at a specific electrode potential. The requirement for fast and reversible color change means that the oxidation-reduction equilibrium for an indicator redox system needs to be established very quickly. Therefore, only a few ...

  9. Table of standard reduction potentials for half-reactions ...

    en.wikipedia.org/wiki/Table_of_standard...

    The values below are standard apparent reduction potentials (E°') for electro-biochemical half-reactions measured at 25 °C, 1 atmosphere and a pH of 7 in aqueous solution. [ 1 ][ 2 ] The actual physiological potential depends on the ratio of the reduced (Red) and oxidized (Ox) forms according to the Nernst equation and the thermal voltage.
