Abstract
Radial distribution functions are computed for the primitive model of an electrolytic solution using the Percus—Yevick and convolution‐hypernetted‐chain integral equations. The results are compared with the Debye—Hückel theory. The Debye—Hückel approximation appears to be particularly bad when the density is great enough that the hard core plays a significant role in determining the radial distribution functions.
