THE STUDY OF CYANIDIN PROTOLYTIC PROPERTIES BY CHEMICAL CHROMATICY METHOD

Abstract

The calculations of chromaticity yellowness index function and the CIE color difference function were made for cyanidin aqueous solutions based on the array of spectrophotometry data in a wide range of medium’s acidity (рН). It was shown the principal possibility to use the yellowness index and CIE color difference chromaticity functions for ionization constants determination of cyanidin.
