Study of the acid-base properties of quercetin in aqueous solutions by color measurements
Acid-base properties of quercetin in aqueous solutions are studied by the method chemical color measurements and dissociation constants (p K ) are determined. The p K values are assigned to corresponding functional groups of quercetin and a probable scheme of their dissociation is proposed. A diagra...
