SUCCESSIVE-SUBSTITUTION METHODS IN CHEMICAL-EQUILIBRIUM CALCULATIONS - AN APPLICATION TO AQUEOUS SIMPLE AMPHOLYTIC ELECTROLYTES

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