Model for determining the diffusion coefficient in electrolyte solutions

In the article, we propose a model for determining the diffusion coefficient in electrolyte solutions. This model is based on the correlation between the plasma state of the charge system and the hydrodynamic approximation of ions in solutions. In this state of matter, many-particle interactions are uniquely formalized by plasma oscillations. To calculate the necessary parameters of the developed model, we have used available reference data on electrical conductivity, generally accepted in chemical thermodynamics. The values of the diffusion coefficient obtained using the proposed calculation formula are consistent with the literature data, which confirms the perspectiveness of this method for assessing diffusion in the system.
