HYDROGEN ION CONCENTRATION OF THE AQUEOUS

Archives of Ophthalmology, 1946
THE value of the glass electrode for determination of the hydrogen ion concentration in the vitreous 1 led to its use for similar investigations on the aqueous humor. The studies were indicated in view of the variations in the physiologic values cited in the literature.

Antifreezing Hydrogel Electrolyte with Ternary Hydrogen Bonding for High‐Performance Zinc‐Ion Batteries

Advances in Materials, 2022
The new‐generation flexible aqueous zinc‐ion batteries require enhanced mechanical properties and ionic conductivities at low temperature for practical applications.

A simple method for determining variations in the hydrogen-ion concentration of the blood

, 1915
Human blood, as it exists in the body, is faintly alkaline in reaction : that is, it has a hydrogen-ion concentration only slightly less than that of pure water, and this degree of alkalinity tends to be maintained even when considerable quantities of ...

HYDROGEN-ION CONCENTRATION OF GASTRIC CONTENTS OF INFANTS

, 1923
Artificially fed infants produce only a small amount of hydrochloric acid during digestion. The amount is not sufficient to show free hydrochloric acid, but brings the stomach contents to a hydrogen-ion concentration of, roughly, 1 × 10−5, orpH5.0.

STUDIES ON THE ACIDITY (HYDROGEN ION CONCENTRATION) OF INFANTS' STOOLS

, 1924
The number of investigations of the exact acidity, that is, the hydrogen ion concentration, of infants' stools reported in the literature are comparatively few.

The measurement of hydrogen ion concentration

Journal of Scientific Instruments, 1924
After a brief summary of the methods which have been used for determining hydrion concentration, the scopes of the conductivity and the hydrogen electrode methods are defined, and the latter is described in detail. The theory of the hydrogen electrode is based on the equilibria at a surface between a noble metal, preferably platinum, and hydrogen in ...

Hydrogen Ion Concentration versus pH

Anesthesia & Analgesia, 1979
There appears to be a tendency to convert pH values into "hydrogen ion concentrations" using the antilog of negative pH values. The present communication describes the thermodynamic basis of pH to explain that the above procedure is erroneous and that pH values should be treated as primary variables. Acidity expressed by the hydrogen ion concentrations

HYDROGEN ION CONCENTRATION IN SALIVA

Archives of Dermatology, 1956
To the Editor : For several years I have been interested in the hydrogen ion concentration in saliva and I have, in my limited way, collected some knowledge regarding it which I believe should be disseminated. Many patients with perleche and some with cheilitis, glossitis, and stomatitis, having failed to respond to routine therapy such as hygiene ...

INTRACELLULAR HYDROGEN ION CONCENTRATION

JAMA: The Journal of the American Medical Association, 1927
To the Editor: —In an editorial (The Journal, July 2) in which the work of Chambers and his co-workers (Chambers, R., and Pollack, H.: J. Gen. Physiol . 10 :739, 1927) was discussed and most deservedly praised, it was emphasized that the intracellular hydrogen ion concentration of living cells is remarkably unchanging and uniform except when the cells
