## Abstract The acidity constants of Alizarine Red S were determined spectrophotometrically at 25 ยฐC and at constant ionic strength 0.1 M (KNO~3~) in pure water as well as in aqueous media containing variable mole percentages (5โ70 %) of organic solvents. The organic solvents used were methanol, et
