    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 ...

  3. Neutral point of view - Wikipedia

    en.wikipedia.org/wiki/Neutral_point_of_view

    Neutral point of view may refer to: Objectivity (science) , the concept of a position formed without incorporating one's own prejudice Neutrality (philosophy) , to maintain neutrality at all times

  4. Pauling's principle of electroneutrality - Wikipedia

    There are two possible structures for hydrogen cyanide, HCN and CNH, differing only as to the position of the hydrogen atom. The structure with hydrogen attached to nitrogen, CNH, leads to formal charges of -1 on carbon and +1 on nitrogen, which would be partially compensated for by the electronegativity of nitrogen and Pauling calculated the net charges on H, N and C as -0.79, +0.75 and +0.04 ...

  5. Ion-neutral complex - Wikipedia

    en.wikipedia.org/wiki/Ion-neutral_complex

    An ion-neutral complex in chemistry is an aggregate of an ion with one or more neutral molecules in which at least one of the partners has a rotational degree of freedom about an axis perpendicular to the intermolecular direction [1] In chemistry, the dissociation of a molecule into two or more fragments can take place in the gas phase, provided there is sufficient internal energy for the ...

  6. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

  7. Neutral particle - Wikipedia

    en.wikipedia.org/wiki/Neutral_particle

    Other neutral particles are very short-lived and decay before they could be detected even if they were charged. They have been observed only indirectly. They include: Z bosons [PDG 4] Dozens of heavy neutral hadrons: Neutral mesons such as the π 0 [PDG 5] and K 0 [PDG 6] The neutral Delta baryon (Δ 0), [PDG 7] and other neutral baryons, such ...

  8. Substitution reaction - Wikipedia

    en.wikipedia.org/wiki/Substitution_reaction

    Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical, and whether the substrate is aliphatic or aromatic. Detailed understanding of a reaction type helps to ...

  9. Base (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Base_(chemistry)

    According to the original formulation of Lewis, when a neutral base forms a bond with a neutral acid, a condition of electric stress occurs. [7] The acid and the base share the electron pair that formerly belonged to the base. [7] As a result, a high dipole moment is created, which can only be decreased to zero by rearranging the molecules. [7]
