Beschreibung:
<jats:p> Acid–base titrations in aqueous and non-aqueous solutions, titrations with metal ions, and analyses of various metal phytates support beyond question the 18-acid structure of phytic acid. Six of the hydrogens are too weakly acidic to be ordinarily titratable in water; in aqueous solution, two distinct breaks occur in the titration curve corresponding to the titration of 8 and 12 protons of phytic acid. </jats:p>
