N2  - Solubility constants for aluminium hydroxides and oxyhydroxides previously obtained (Raupach 1963a) were supported by further studies at 20° and 50°. Polymeric aluminium ions were not present in systems obeying      Ks1  =  -log [ AlOH2+) (OH-) 2]  =  23.31 at 25°C When 5 < -log [AlOH2+] < 3 no Al3+ ions are found in solution because the aluminium hydroxide surface readily binds Al3' ions, produced slowly in solution, and releases AlOH2+ ions. This also happens in soil solutions.
