Daftar Isi:
- The citrate complex of beryllium has been studied in the pH range of 2.6 to 6.0. Beryllium ions react with citric acid and form in the lower pH region a neutral complex (C) liberating two protons according to the reaction : Be2++ H3Cit \(\rightleftharpoons\) C+ 2H+ • • • • • • (i) In the higher pH range this neutral complex dissociates like a dibasic acid to complexes C1\(-\) and C22\(-\) according to reactions (ii) and (iii): C \(\rightleftharpoons\) C1\(-\) + H+ • • • • • • (ii) C1\(-\)\(\rightleftharpoons\)C22\(-\) + H+ • • • • • • (iii) .. The equilibrium constants of reactions (i), (ii), and (iii) are found to be 4.52 X 10-4, 2.41 X 10-4, and 4.95 x 10-6 respectively.
