  2. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. [ 1 ] [ 2 ] The amount of product formed is limited by this reagent, since the reaction cannot continue without it.

  3. Protecting group - Wikipedia

    en.wikipedia.org/wiki/Protecting_group

    The procedure begins actually with redox chemistry at the protected phosphorus atom. A tricoordinate phosphorus, used on account of the high reactivity, is tagged with a cyanoethyl protecting group on a free oxygen. After the coupling step follows an oxidation to phosphate, whereby the protecting group stays attached.

  4. Reagent - Wikipedia

    en.wikipedia.org/wiki/Reagent

    In chemistry, a reagent (/ r i ˈ eɪ dʒ ən t / ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. [1] The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. [1]

    A chemical reaction is a process that ... and thus induces a reduction in the other species and is considered the reducing agent. ... Chemistry; Combustion; Limiting ...

  6. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    The limiting reagent is the reagent that limits the amount of product that can be formed and is completely consumed when the reaction is complete. An excess reactant is a reactant that is left over once the reaction has stopped due to the limiting reactant being exhausted.

  7. Reducing agent - Wikipedia

    en.wikipedia.org/wiki/Reducing_agent

    In chemistry, a reducing agent (also known as a reductant, reducer, or electron donor) is a chemical species that "donates" an electron to an electron recipient (called the oxidizing agent, oxidant, oxidizer, or electron acceptor).

  8. Flux (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Flux_(metallurgy)

    Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent.

  9. Glossary of chemistry terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_chemistry_terms

    A chemical compound consisting of a central atom or ion, usually metallic and known as the coordination center, bonded to a surrounding array of other groups of atoms, e.g. molecules or ions, which are known as ligands or complexing agents. Many metal-containing compounds, especially those of the transition metals, are coordination complexes.
