| Abstract: | Ionization constants have been obtained for several aromatic arsonic acids and the values correlated with the structural effects of the substituents. The Hammett equation was obeyed in the case of para-substituted acids and ϱ values for the successive ionizations of phenylarsonic acids were determined. Hammett σ values for the substituents AsO3H2, AsO3H− and AsO32− were also obtained. |
