The interference of magnesium and strontium with the EGTA complexometric titration of calcium was insignificant at the level of accuracy used for the molar ratios found in seawater. Interference effects were found, however, for samples containing higher magnesium or strontium to calcium ratios. An average value of 0.02103 (SD +- 0.00001) was obtained for Ca:Cl per thousand for nine bottles of IAPSO Standard Seawater (P79, 1.9376 Cl%).
