The dissociation degrees of bromophenol blue at various total ionic strengths in pure water and in 15%, 25 mass% ethanol-water mixed solvents were measured by U-3200 spectrophotometer, and the pH values of corresponding solution were also measured by Orion EA 940 ionometer. The thermodynamic dissociation constants of bromophenol blue in pure water and in the mixed solvents were determined by two methods: extrapolation and polynomial approximation. The effect of medium on absorption spectra of bromophenol blue was discussed.
