Abstract Based on the analytical study of the solutions to the coronal balance equations, as well as on the numerical results, it is shown that, in many cases of practical interest, it is possible to describe the impurity ionization state with acceptable accuracy by only the two or three most representative ionization states. Reduced models for light impurities and strongly ionized heavy impurities in coronal hydrogen plasmas are proposed. The models make it possible to obtain analytical results for many cases as well as to significantly reduce computation time. In these approximations, simple equations determining the dynamics of impurity distributions over ionization states are derived.
