Obtaining new fundamental data on the transport properties of the studied ions in these solvents that are absent in the literature popup.description2  Object of study: protic and aprotic solvents (light and heavy water, formic acid, acetone, dimethyl sulfoxide), single-charged cations and anions. The aim of the study: to conduct a comprehensive physics-chemical investigation of ion-molecular electrolyte systems based on protic and aprotic solvents. Obtaining new fundamental data on the transport properties of single-charged ions in these solvents, which are not available in the literature. Methods and apparatus: experimental (conductivity, viscometry) mathematical processing of the experiment. Results: New data on the diffusion coefficients and microscopic characteristics of the diffusion shift length ( ) of single-charged ions (lyonium-ions (H3O+; D3O+; HCOOH2+, (СН3)2СОН+, (СН3)2SОН+), Li+, Na+, K+, Rb+, Cs+, Me4N+, Et4N+, Pr4N+, Bu4N+, Pe4N+, F–, Cl–, Br–, I–, ClO4–, CSN–, NO3–, HCOO–, BPh4–) in light and heavy water, formic acid , acetone and dimethyl sulfoxide at 298.15 K based on the literature data on the limiting molar electrical conductivity of these ions. It is shown that the parameter correlates with the type of ion solvation: at values > ri (ri is ion structural radius), the latter is positively solubilized, and when < ri, negative solvation is observed. Novelty: The main scientific novelty of the research results lies in the use of the parameter ( - ri) to determine the type of near ion solvation. This is a definite step forward in terms of the study of ion solvation and the use of the diffusion displacement of an ion for this purpose. It is shown that the parameter not only has a physical meaning, but also should be used to determine the type of near-solvation of ions. Scope and area of possible application: further development of ion solvation theory in protolytic and aprotic solvents at various parameters of the state of liquid electrolytic systems, creation of liquid-phase functional materials based on them.
