WebSep 1, 2003 · Since the pKa of the aromatic thiol is much lower than those of aliphatic compounds, we determined the pKa of thiophenol in aqueous solutions of 0.4 M acrylamide. Measurements of absorbance at 260 nm as a function of pH gave a pKa of 6.7, that agrees with the literature value of 6.8 in bulk water [9].
