Comparison of electrolytic conductivity theories: Performance of classical and new theories

Conductivity equations, based on the mean spherical approximation (MSA), have recently been derived. We compare their performance with that of classical equations at the level of experimental uncertainty using conductivity data for some typical electrolyte solutions. For symmetrical electrolytes, th...
