The molar ionic conductivity of each ionic species is proportional to its electrical mobility (μ), or drift velocity per unit electric field, according to the equation = where z is the ionic charge, and F is the Faraday constant. [9]
where + and are the numbers of cations and anions respectively per formula unit of electrolyte. [1] In practice the molar ionic conductivities are calculated from the measured ion transport numbers and the total molar conductivity.
Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of measuring the ionic content in a ...
[1] [2] [3] For example, if a 1 m 3 solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m. Electrical conductivity (or specific conductance) is the reciprocal of electrical resistivity. It represents a material's ability to conduct ...
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.
AlN has high thermal conductivity, high-quality MOCVD-grown AlN single crystal has an intrinsic thermal conductivity of 321 W/(m·K), consistent with a first-principle calculation. [5] For an electrically insulating ceramic , it is 70–210 W/(m·K) for polycrystalline material, and as high as 285 W/(m·K) for single crystals).
Chemical formula. C 2 H 3 Li O 2: Molar mass: 65 ... Molar mass: 65.98 g·mol −1 ... It has a lower electrical conductivity and can be run at higher speeds than can ...
The carrier density is important for semiconductors, where it is an important quantity for the process of chemical doping. Using band theory, the electron density, is number of electrons per unit volume in the conduction band. For holes, is the number of holes per unit volume in the valence band.
