THE pH OF SEA WATER AS MEASURED WITH THE GLASS ELECTRODE

ERIC G. BALL 1 and C. CHESTER STOCK 1

1 From the Marine Biological Laboratory, Woods Hole, Mass., and the Department of Physiological Chemistry, the Johns Hopkins University School of Medicine, Baltimore, Maryland

The hydrogen electrode and the glass electrode registered approximately the same pH values for various buffer solutions in which dry sea salt was dissolved to give a concentration similar to that found in sea water. A direct comparison of the two methods on sea water was not possible because the behavior of the hydrogen electrode was erratic in this poorly buffered medium. It is concluded that the salt content of sea water does not interfere with the application of the glass electrode to the determination of the pH of sea water and that such determinations may be made with a fair degree of accuracy (± 0.03 pH). The pH value of several samples of sea water have been determined and their differences discussed.
