    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  4. Reactivity - Wikipedia

    en.wikipedia.org/wiki/Reactivity

    Reactivity may refer to: Reactivity (chemistry) , the rate at which a chemical substance tends to undergo a chemical reaction Reactive programming , a property of an execution model whereby changes are automatically propagated through a dataflow network

  5. Leaving group - Wikipedia

    en.wikipedia.org/wiki/Leaving_group

    In chemistry, a leaving group is defined by the IUPAC as an atom or group of atoms that detaches from the main or residual part of a substrate during a reaction or elementary step of a reaction. [1] However, in common usage, the term is often limited to a fragment that departs with a pair of electrons in heterolytic bond cleavage. [2]

  6. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    The reaction takes place in the active site, a small part of the enzyme which is usually found in a cleft or pocket lined by amino acid residues, and the rest of the enzyme is used mainly for stabilization. The catalytic action of enzymes relies on several mechanisms including the molecular shape ("induced fit"), bond strain, proximity and ...

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

  8. Reactivity series - Wikipedia

    In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] ...

  9. Chemical stability - Wikipedia

    en.wikipedia.org/wiki/Chemical_stability

    The reactivity of a chemical substance is a description of how it might react across a variety of potential chemical systems and, for a given system, how fast such a reaction could proceed. Chemical substances or states can persist indefinitely even though they are not in their lowest energy state if they experience metastability — a state ...
