Abstract
The dissociation and the possible association of saolicylic acid was investigated by spectrophotometric measurements and potentiometric titrations of the 2.26 X 10-4 M and 4 X 10-3 M acid. A discrepancy between the experimental colorimetric titration curve and the calculated one between pH 3 and pH 4 was stated. This phenomenon is explained by the assumption that some association reactions might occur. The calculation of the association constants was attempted by means of the least squares method using the titration data obtained.
