estimation of the diffusion coefficient and hydrodynamic radius (stokes radius) for inorganic ions in solution depending on molar conductivity as electro-analytical technique-a review

Diffusion coefficient (d) and radiuses of inorganic charge ions (r) in different environments is of importance in scientific fields, explaining certain features of ions. d values were obtained using the einsteinsmoluchowski equation depending on limiting molar conductivity (λ^o) of inorganic charge ions. inorganic ions have d values at the range of 1^−3×10^−9 m^2.s^1,except hydroxyl and hydrogen ion (5.2×10^−9 and 9.1×10^−9 m^2.s^1, respectively). the hydrodynamic radius r for diffusing ions was calculated using the stokes–einstein equation based on d values. inorganic ionshaver, values at the range of 1^−3×10^−10 m, except hydroxyl and hydrogen ion (r=0.47×10^−10 and 0.27×10^−10 m, respectively).
