Hi All,<br><br>I would like to find the stoichiometry for the chelation of a calcium ion (Ca 2+) with a citrate ion (citrate 3-), as well as the equilibrium constant or free energy of calcium-citrate complex formation.<br>
<br>x*Ca2+  +  y*citrate3-  &lt;=&gt;  z*calcium-citrate-complex  (x, y, and z are the stoichiometric coefficients)<br><br>Thanks in advance,<br>Nancy<br><br>
