What is it about?
It is hard to predict what different electrolytes will do in different systems (e.g. batteries, cooking, agriculture, mineral processing, biological). The important properties of the electrolytes themselves were relatively unknown. This paper is a meta-analysis of existing properties and a development of new properties, to see how well they relate to experimental outcomes. A new parameter, the radial charge density of the interacting atom, has many linear correlations with various experiments. This should approximate the overall electrostatic interaction.

Why is it important?
It has now been over 130 years since Franz Hofmeister initially found common trends in electrolyte behaviour. However, these have been difficult to quantify and therefore hard to predict. We have now quantified this series for anions building a framework for predictions.
