  2. Ion transport number - Wikipedia

    en.wikipedia.org/wiki/Ion_transport_number

    In practice the molar ionic conductivities are calculated from the measured ion transport numbers and the total molar conductivity. For the cation + = + +, and similarly for the anion. In solutions, where ionic complexation or associaltion are important, two different transport/transference numbers can be defined.

  3. Goldman–Hodgkin–Katz flux equation - Wikipedia

    en.wikipedia.org/wiki/Goldman–Hodgkin–Katz...

    The Goldman–Hodgkin–Katz flux equation (or GHK flux equation or GHK current density equation) describes the ionic flux across a cell membrane as a function of the transmembrane potential and the concentrations of the ion inside and outside of the cell.

  5. Project Euler - Wikipedia

    en.wikipedia.org/wiki/Project_Euler

    Project Euler (named after Leonhard Euler) is a website dedicated to a series of computational problems intended to be solved with computer programs. [1] [2] The project attracts graduates and students interested in mathematics and computer programming.

  6. Spectator ion - Wikipedia

    en.wikipedia.org/wiki/Spectator_ion

    They are present in total ionic equations to balance the charges of the ions. Whereas the Cu 2+ and CO 2− 3 ions combine to form a precipitate of solid CuCO 3. In reaction stoichiometry, spectator ions are removed from a complete ionic equation to form a net ionic equation. For the above example this yields:

  7. Ion-selective electrode - Wikipedia

    en.wikipedia.org/wiki/Ion-selective_electrode

    This device will have an input signal, a property that we wish to quantify, and an output signal, a quantity we can register. In this case, ion selective electrode are electrochemical sensors that give potentiometric signals. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation ...

  8. Chemical equilibrium - Wikipedia

    en.wikipedia.org/wiki/Chemical_equilibrium

    For this reason, equilibrium constants for solutions are usually determined in media of high ionic strength. K c varies with ionic strength, temperature and pressure (or volume). Likewise K p for gases depends on partial pressure. These constants are easier to measure and encountered in high-school chemistry courses.

  9. Kröger–Vink notation - Wikipedia

    en.wikipedia.org/wiki/Kröger–Vink_Notation

    The following oxidation–reduction tree for a simple ionic compound, AX, where A is a cation and X is an anion, summarizes the various ways in which intrinsic defects can form. Depending on the cation-to-anion ratio, the species can either be reduced and therefore classified as n-type , or if the converse is true, the ionic species is ...
