摘要：

The influence of random errors in measuring the potential and dosing the titrant volume on the reliability of the parameters of redox titration calculated using logarithmic relationships has been studied. It is found that the propagation of measurement errors in this case mostly depends on the difference between the real potentials of the reacting redox couples, on the number and distribution of points in the titration curve, and on the stoichiometry of the reaction.
