摘要
The interaction parameters of strong electrolytes obtained for both the molar and molal scales using the Modified Bromley's Methodology (MBM) have been correlated with the ionic charge and individual crystal radius of each ion. The correlation function for each ion with opposite counterions is a straight line centered in the water radius value (1.39 X 10(-10) m). These correlations allow the prediction of values of unknown interaction parameters of a cation with several anions even if only one interaction parameter of the cation with a given anion is known.
