PROGNOSTICATION CRITERION OF POTENTIAL AND PRACTICAL USE OF ANALYTICAL REAGENTS IN TITRIMETRIA OF INDIVIDUAL SUBSTANCES

Various possible criterion in titrimetric methods have been discussed in this paper and more informative, visual and universal criterion-the degree of proceeding of individual reaction at the equivalence point have been chosen. The equation for the degree of proceeding of individ ual analytical reaction suited for any chemical reactions under real c onditions with an allowance made for both component and titrant concen tration have been deduced. This criterion allows us to make a prognosi s of any parametres of a titrimetric procedure of an individual substa nce determination and the procedure as a whole, not having carried out the experiment.
