WebDec 22, 2024 · There is no exact measure of radii in both DH theory and the Born theory of solvation. 34 Generally, it is accepted that the relevant measure of radii in solution should be somewhere between the "bare" ionic radii and the size of a solvated ion-cluster. 22 As expected, the crystallographic ("bare") ionic radii 50 shown in Table I are the smallest. east bay internet providersWebThe most obvious approach to estimate the ion size parameter is the sum of the crystallographic radii of the cation and anions present in the electrolytic-solution. This is because the two ions cannot come closer than the sum of their individual ionic radii.
