  2. Pauling's principle of electroneutrality - Wikipedia

    en.wikipedia.org/wiki/Pauling's_principle_of...

    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 ...

  3. 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.

    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 ...

  5. 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]

  6. 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 ...

  7. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. [ 16 ] [ 17 ] [ 18 ] A molecule may be homonuclear , that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O 2 ); or it may be heteronuclear , a chemical compound composed of more than one element, as with ...

  8. Electrodialysis - Wikipedia

    en.wikipedia.org/wiki/Electrodialysis

    Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell.

  9. Isolobal principle - Wikipedia

    en.wikipedia.org/wiki/Isolobal_principle

    For example, a MoL 6 complex is d 6 and neutral. However, removing a ligand to form the first frontier orbital would result in a MoL − 5 complex because Mo has obtained an additional electron making it d 7. To remedy this, Mo can be exchanged for Mn, which would form a neutral d 7 complex in this case, as shown in Figure 3. This trend can ...
