<jats:title>Abstract</jats:title><jats:p>The 12 pK<jats:sub>a</jats:sub> values for phytic acid have been obtained from pH titration data and nonlinear regression analysis. The pK<jats:sub>a</jats:sub> values ranged from 1.9 to 9.5. The results are discussed in terms of previously determined pK<jats:sub>a</jats:sub> values. Possible reasons are given for the differences between previously determined values and present values.</jats:p>
