As the concentration of inert ions is increased to 0.001 M and above, the effects of
electrostatic ion interaction become increasingly important, stabilizing the ions in
solution (see Topics E1 and E2) and leading to greater ion dissociation. Thus the activity
coefficients, γ, become significantly less than unity and the solubility, s, increases. Values
of γ at any ion concentration can be calculated by using Debye-Hückel theory (see Topic
E2), which allows the calculation of s.
