Solubility products of Al(OH)3 were determined in various solutions of NH4+, Li+, Na+, K+, and Ca2+ ions. Increasing amounts of these hydroxides were added to the respective chloride solutions containing aluminum chloride. The solutions were aged for 3 months. Activities of the OH− ions were calculated from the pH values of the solutions. The total Al concentrations remaining in solutions were determined by Hsu's modified aluminon method. The Al3+ ion concentrations were computed using the hydrolysis equilibria of Aveston. The ion product, aAl3+(aOH−)3, was found to vary linearly with the [OH]/[Al] ratio. The solubility product of Al(OH)3 was obtained by extrapolating this ratio to 3. The pKsp values thus obtained were 30.55, 33.15, 30.75, 30.36, and 31.00 in NH4+, Li+, Na+, K+, and Ca2+ systems respectively. The anomalously low solubility product of Al(OH)3 in the Li+ system was attributed to the specific "lithium effect".

Experiments were made to determine the relative amounts of solid phase hydroxyaluminum to polynuclear ionic hydroxyaluminum formed, according to methods developed by one of the authors, during titrations of dilute AlCl3 solutions with a base. With both 10−3 and 10−2 M AlCl3 solutions, and with both fast (less than 5 minutes) and slow (12 hours) titrations, the solid phase and the polynuclear ions were present at each degree of neutralization at which measurements were made. During the greater part of the titrations the solid phase was the major product with the fast titrations, and the polynuclear ions were the major product with the slow titrations. Beyond about 80% neutralization the polynuclear ions began to decrease in concentration until at 100% the solid phase approached 100% of the products regardless of the rate of titration. There was a considerable amount of Cl associated with the solid phase during most of each titration, but the Cl/Al molar ratio of the solid approached zero as neutralization approached 100%.
