HYDROGEN ION CONCENTRATION OF THE AQUEOUS
Archives of Ophthalmology, 1946THE 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.

The measurement of hydrogen ion concentration
Journal of Scientific Instruments, 1924After 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, 1979There 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, 1956To 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, 1927To 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

HYDROGEN-ION CONCENTRATION OF PROTOZOAN CULTURES [PDF]
The Biological Bulletin, 1921 The chemical changes taking place in ordinary hay infusions used for protozoan cultures have been described by various authors, among whom may be mentioned Peters' and Fine.2 The points of interest discussed by these two authors are the changes occurring in the titratable acidity and alkalinity of such infusions. .

A UNIVERSAL INDICATOR FOR HYDROGEN ION CONCENTRATION
JAMA: The Journal of the American Medical Association, 1927A single solution that will give a continuous change of color with changes in hydrogen ion concentration over nearly the entire range, from strongly acid to strongly alkaline solutions, may serve a multitude of purposes in the clinical and scientific laboratory. Such a mixture, suggested by Moirs of South Africa in 1917, is marketed by the British Drug
