  2. Reducing agent - Wikipedia

    en.wikipedia.org/wiki/Reducing_agent

    Reducing agents and oxidizing agents are the ones responsible for corrosion, which is the "degradation of metals as a result of electrochemical activity". [3] Corrosion requires an anode and cathode to take place. The anode is an element that loses electrons (reducing agent), thus oxidation always occurs in the anode, and the cathode is an ...

  3. Oxidizing agent - Wikipedia

    en.wikipedia.org/wiki/Oxidizing_agent

    The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).

  4. Redox titration - Wikipedia

    en.wikipedia.org/wiki/Redox_titration

    A redox titration [1] is a type of titration based on a redox reaction between the analyte and titrant. It may involve the use of a redox indicator and/or a potentiometer. A common example of a redox titration is the treatment of a solution of iodine with a reducing agent to produce iodide using a starch indicator to help detect the endpoint.

  5. Reduction potential - Wikipedia

    en.wikipedia.org/wiki/Reduction_potential

    Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals. 2 Li (s) + H 2 (g) → 2 LiH (s) [a] Hydrogen (whose reduction potential is 0.0) acts as an oxidizing agent because it accepts an electron donation from the reducing agent lithium (whose reduction potential is -3.04), which causes ...

  6. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    In E. coli, for example, oxidative phosphorylation can be driven by a large number of pairs of reducing agents and oxidizing agents, which are listed below. The midpoint potential of a chemical measures how much energy is released when it is oxidized or reduced, with reducing agents having negative potentials and oxidizing agents positive ...

  7. Chemoselectivity - Wikipedia

    en.wikipedia.org/wiki/Chemoselectivity

    A famous example is the Luche Reduction, where an oxophilic metal makes the carbonyl of a conjugated ketone more reactive and directs the reducing agent. [6] On the other hand, copper organometallics have high affinity with carbon-carbon multiple bonds and are used for conjugate addition of nucleophiles into a conjugated ketone.

  8. Oxidizing acid - Wikipedia

    en.wikipedia.org/wiki/Oxidizing_acid

    An oxidizing acid is a Brønsted acid that is a strong oxidizing agent. Most Brønsted acids can act as oxidizing agents, because the acidic proton can be reduced to hydrogen gas. Some acids contain other structures that act as stronger oxidizing agents than hydrogen ions. Generally, they contain oxygen in their anionic structure.

  9. Frost diagram - Wikipedia

    en.wikipedia.org/wiki/Frost_diagram

    The Frost diagram normally shows free-energy values above and below nE° = 0 and is scaled in integers. The y axis of the graph displays the free energy. Increasing stability (lower free energy) is lower on the graph, so the higher free energy and higher on the graph a species of an element is, the more unstable and reactive it is. [2]
