Abstract
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.
