The Hydrogen-Ion Concentration of Cholera Stools

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...

Effect of hydrogen ion concentration on lactate dehydrogenase (LD) assays.

Union of Pure and Applied Chemistry (IUPAC) contained recommendations for names and symbols for quantities in chemistry and physics (1). The recommendation concerning the writing of the name (symbol) of a given chemical quantity was exemplified as follows: V(K2S04, 0.1 mol dm3 in H2O, 25#{176}C) = 48 cm3 mol-'. It was up to the reader to interpret this as the molar volume of potassium sulfate i...
