Recently, there has been a lot of interest in the properties of screening phenomena in concentrated electrolytes. Molecular dynamics simulations were conducted on an aqueous NaCl solution to investigate the cluster-size distribution of cations and anions. The cluster-size distribution showed power-law decay behavior at sufficiently high concentrations. Additionally, the fraction of isolated ions without pairing or clustering was studied. The study clarifies the statistical physics of cations and anions in concentrated electrolytes.
Recently, the properties of screening phenomena in concentrated electrolytes have attracted considerable attention. Molecular dynamics (MD) simulations were performed on an aqueous NaCl solution, and the clustersize distribution of cations and anions was clarified. The cluster-size distribution exhibited approximately powerlaw decay behavior with a sufficiently high concentration. In addition, the fraction of isolated ions without pairing or clustering was also investigated. In concentrated electrolytes, the number of isolated ions does not significantly depend on the electrolyte concentration. This study clarifies the statistical physics of the cations and anions in concentrated electrolytes.
