Query: Calculation of chemical reactions in electrophoresis   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.
