%X The equilibrium reactions of isocitrate with protons and Al3+ have been studied by potentiometric titration in aqueous 0.10 M KCl at 25&#176;C. The protonation constants, corrected for K+-isocitrate complexing , were log&#946;0,1,1 = 5.838, log&#946;0,2,1 = 10.126 and log&#946;0,3,1 = 13.219. The stabilities and stoichiometries of the complexes, AlpHqLr, were defined by the constants log&#946;1,1,1 = 9.55(05), log&#946;1,0,1 = 6.90(02), log&#946;1,-1,1 = 3.06(04) and log&#946;2,-3,2 = 4.08(04) or log&#946;3,-4,3 = 10.36(06). Compared with the Al3+-citrate system, complexes are of lower thermodynamic stability, but equilibrate more rapidly.
