Successive‐substitution methods in chemical‐equilibrium calculations: An application to aqueous simple ampholytic electrolytes

Abstract For each of the aqueous electrolytes, whose acid‐base behaviour is described by only one acidic, and only one basic, ionization equilibrium, the electroneutrality equation is rearranged (as described in Appendix) to such a form that the successive‐substitution algorithm to which it can give origin always converges to the root of the corresponding equation, i. e., to the hydrogen‐ion concentration of the solution it refers to. The converging properties of these algorithms are given a qualitative explanation.
