Abstract
We have combined results of earlier measurements leading to equilibriu m constants for formation and reaction of aluminum-citrate complexes i n aqueous solution at 298.15 K with results of our calorimetric measur ements at this same temperature to obtain Delta H values for reactions of Al3+(aq) with citrate ions. Results of some of these calorimetric measurements also lead to a value of Delta H+ for the reaction Al3+(aq ) + 4 OH-(aq) = Al(OH)(4)(-)(aq).
