  2. Ion transport number - Wikipedia

    en.wikipedia.org/wiki/Ion_transport_number

    The practical importance of high (i.e. close to 1) transference numbers of the charge-shuttling ion (i.e. Li+ in lithium-ion batteries) is related to the fact, that in single-ion devices (such as lithium-ion batteries) electrolytes with the transfer number of the ion near 1, concentration gradients do not develop. A constant electrolyte ...

  3. Liquid junction potential - Wikipedia

    en.wikipedia.org/wiki/Liquid_junction_potential

    Liquid junction potential (shortly LJP) occurs when two solutions of electrolytes of different concentrations are in contact with each other. The more concentrated solution will have a tendency to diffuse into the comparatively less concentrated one.

  4. Electrolyte - Wikipedia

    en.wikipedia.org/wiki/Electrolyte

    Electrolytes may enter or leave the cell membrane through specialized protein structures embedded in the plasma membrane called "ion channels". For example, muscle contraction is dependent upon the presence of calcium (Ca 2+), sodium (Na +), and potassium (K +). Without sufficient levels of these key electrolytes, muscle weakness or severe ...

  5. Amphoterism - Wikipedia

    en.wikipedia.org/wiki/Amphoterism

    Amphoteric is derived from the Greek word amphoteroi (ἀμφότεροι) meaning "both".Related words in acid-base chemistry are amphichromatic and amphichroic, both describing substances such as acid-base indicators which give one colour on reaction with an acid and another colour on reaction with a base.

  6. Ionic strength - Wikipedia

    en.wikipedia.org/wiki/Ionic_strength

    The molar ionic strength, I, of a solution is a function of the concentration of all ions present in that solution. [3]= = where one half is because we are including both cations and anions, c i is the molar concentration of ion i (M, mol/L), z i is the charge number of that ion, and the sum is taken over all ions in the solution.

  7. Solid-state electrolyte - Wikipedia

    en.wikipedia.org/wiki/Solid-state_electrolyte

    Quasi solid-state electrolytes (QSSEs) are a wide class of composite compounds consisting of a liquid electrolyte and a solid matrix. This liquid electrolyte serves as a percolating pathway of ion conduction while the solid matrix adds mechanical stability to the material as a whole. As the name suggests, QSSEs can have a range of mechanical ...

  8. Specific ion interaction theory - Wikipedia

    en.wikipedia.org/wiki/Specific_ion_interaction...

    In theoretical chemistry, Specific ion Interaction Theory (SIT theory) is a theory used to estimate single-ion activity coefficients in electrolyte solutions at relatively high concentrations. [1] [2] It does so by taking into consideration interaction coefficients between the various ions present in solution.

  9. Supporting electrolyte - Wikipedia

    en.wikipedia.org/wiki/Supporting_electrolyte

    A supporting electrolyte, in electrochemistry, according to an IUPAC definition, [1] is an electrolyte containing chemical species that are not electroactive (within the range of potentials used) and which has an ionic strength and conductivity much larger than those due to the electroactive species added to the electrolyte.
