Citrate Complex

centration formation constants for magnesium and calcium citrate complexes have been redetermined from pH titrations of citric acid in the absence and presence of the divalent metal ions in aqueous solution at 2° Values for the constants, corrected for the presence of potassium citrate complex, are presented and critically compared with literature values. Values for the formation constants of strontium and barium citrate complexes are also reported.
