Notes on the measurement of hydrogen ion concentration

Design of Hydrogen Ion Concentration Measurement System

This paper presents an application for measuring the concentration of hydrogen ion by using ion selective electrodes. By this research we hope to provide useful information and verify the feasibility of measuring the concentration of other ions in the same way for sensing sweat. In this research, a pH electrode is used to generate an electrical potential which reflects the concentration of hydr...

The Hydrogen-Ion Concentration of Human Fæces

Howe and Hawk (1912) were the first to determine the exact hydrogen-ion concentration of human fjeces. They examined samples of fa}ces from three individuals and found that the reaction of the material examined by them was always alkaline, varying with the different subjects and conditions from pH 7.01 to 8.77. Nelson and Williams (1916) recorded that 29 of the 30 individuals examined by them p...

The Effect of Hydrogen Ion Concentration on Saponin Hemolysis

The purpose of the present study has been to determine the change in the resistance of corpuscles to saponin with changes in pII., the acids employed being the common inorganic acids. Ponder (1) has shown that the rate of saponin hemolysis is increased in the presence of certain acids and has applied the equation Cl = R (C, + g) to systems in which an acid is the accelerating agent. Details of ...
