MULTIWAVELENGTH SPECTROPHOTOMETRIC DETERMINATION OF THE ACIDITY CONSTANT OF NITROSO-R-SALT IN VARIOUS MICELLAR MEDIA SOLUTIONS

The investigation of the dissociation equilibrium of Nitroso-R-Salt (NRS) in aqueous micellar solution was determined spectrophotometrically at 25°C and at the constant ionic strength I = 0.1 M KNO3. For this purpose, the effect of nonionic (Triton X-100), cationic (CTAB), and anionic (SDS) surfacta...
