Abstract

The main goal of the work is to find stationary solutions of the equations of chemical kinematics for mixtures of complex composition. According to the given research goal the system of nonlinear equations for determining the equilibria of reversible chemical dissociation reactions was obtained and transformed in the work, an algorithm for solving the problem for tris-borate mixture was created and tested, allowing to calculate the pH of the solution taking into account the ionic force at given concentrations of the initial reagents of the mixture, as well as to process the results.
