The results leads to a reaction scheme with the species AlOH2+, Al(OH)2 + and H2 L 2− in Al(III) solutions "not prebuffered”, in Al(III) solutions "prebuffered” additionally the species AlClac 2−. The difference in the course of the functionsk exp =f[c 0(Al);c(H+)] in the Al(III) solutions not prebuffered respective prebuffered was explained: Chromotrophic acid as de facto neutral ligand does not react — contrary to the anionic ligands — with the dimeric Al(III) species present in the Al(III) solutions prebuffered. Water exchange rate constants for the contributing species according to the Eigen-Tamm-model were evaluated and correspond very well with the expected values.
