  2. Ion association - Wikipedia

    en.wikipedia.org/wiki/Ion_association

    In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...

  3. Ion exchange - Wikipedia

    en.wikipedia.org/wiki/Ion_exchange

    Ion-exchange resin beads Ion-exchange column used for protein purification. Ion exchange is a reversible interchange of one species of ion present in an insoluble solid with another of like charge present in a solution surrounding the solid. Ion exchange is used in softening or demineralizing of water, purification of chemicals, and separation ...

  4. Electron transfer - Wikipedia

    en.wikipedia.org/wiki/Electron_transfer

    As an example, self-exchange describes the degenerate reaction between permanganate and its one-electron reduced relative manganate: [MnO 4 ] − + [Mn*O 4 ] 2− → [MnO 4 ] 2− + [Mn*O 4 ] − In general, if electron transfer is faster than ligand substitution, the reaction will follow the outer-sphere electron transfer route.

  5. Ion-exchange membrane - Wikipedia

    en.wikipedia.org/wiki/Ion-exchange_membrane

    An ion-exchange membrane is a semi-permeable membrane that transports certain dissolved ions, while blocking other ions or neutral molecules. [1] Ion-exchange membranes are therefore electrically conductive. They are often used in desalination and chemical recovery applications, moving ions from one solution to another with little passage of ...

  9. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    Thus, the term "ionic bonding" is given when the ionic character is greater than the covalent character – that is, a bond in which there is a large difference in electronegativity between the cation and anion, causing the bonding to be more polar (ionic) than in covalent bonding where electrons are shared more equally.
