Spectrophotometric Determination of the Ionization Constant of Dimethylpicric Acid (2,4,6-Trinitro-3,5-xylenol) in Water at 25 °C

The ionization constant of dimethylpicric acid (2,4,6-trinitro-3,5-xylenol) in water at 25 °C has been determined by a spectrophotometric method. The pK value 1.38 (K ≈0.042) was obtained. Potentiometric titrations, although less precise, yielded a pK value of the same magnitude.
