Colorimetric and asid-base characteristics of pyrogallol red and bromopyrogallol red


Dissociation constants for pyrogallol red and bromopyrogallol red have been determined at ionic strength of 0,126-0,526 in 1,6% ethanol in water by spectrophotometric and colorimetric methods. Molar absorptivity and molar coefficients of colorimetric function was determined for individual forms of reagents.
