abstract = {We present an application of the Kirkwood–Buff theory,
which is introduced to describe the influence of cosolutes
on the chemical equilibrium between dissociated and
associated ion pairs in ternary electrolyte solutions. Our
approach makes use of Kirkwood–Buff integrals and the
introduction of a local/bulk partition model. The cosolute
species can be either charged or uncharged, and our approach
is applicable for ideal and weak nonideal solutions in
combination with low ion concentrations. As the main result,
the theory reveals that differences in the local cosolute
accumulation behavior around the ions induce a shift of the
chemical equilibrium either to the associated or the
dissociated state. The findings of our analysis are useful
for a deeper understanding of electrolyte solutions in
modern electrochemical storage devices. All results are
verified by atomistic molecular dynamics simulations in
terms of sodium chloride pairs in dimethylacetamide–water
mixtures.},
