    Notes: Acidity constants at 20° C and the ionic strength μ = 0,1 were determined for 2-benzenesulfonamido-pyridine, 2-benzenesulfonamidopyrimidine, 2-sulfanilamido-pyridine, 2-sulfanilamido-pyrimidine, 2-sulfanilamido-4-methyl-pyrimidine, 2-sulfanilamido-4,6-dimethyl-pyrimidine, 4-sulfanilamido-2,6-dimethyl-pyrimidine and 2-sulfanilamido-thiazole. The effects of substituents on the pK values are discussed. The data may be explained by the existence of tautomeric forms for some substances investigated in this work.
