The Yellowness Index Use for the Acid-Base Equilibrium Study in Xylenol Orange Aqueous Solutions

Abstract

The possibility of the yellowness index use for the acid-base equilibrium study and ionization constants determination in dyes solutions is studied. It is shown that the yellowness index is suitable for the set task. Its use enables a more reasonable mathematical apparatus algorithmization, automation, simplification and in comparison with the existing approaches of the chemical chromaticity method and classical physico-chemical methods.
