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 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.

Seawater Hydrogen-Ion Concentration: Vertical Distribution

Science, 1968
Two major processes that affect the vertical distribution of hydrogen-ion concentration in the sub-Arctic region of the northeastern Pacific Ocean are the apparent oxygen utilization by marine organisms and, to a lesser extent, carbonate dissolution.

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

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 ...

HYDROGEN ION CONCENTRATION OF TEARS

Archives of Ophthalmology, 1935
At present the treatment of conjunctival and corneal lesions is almost entirely symptomatic and empirical and, in many instances, thoroughly illogical. Two years ago one of us (G. N. H.) called attention to the frequent misuse of the ointment of yellow mercuric oxide (Pagenstecher's ointment) 1 and stated that much of its reputation for improving all ...

HYDROGEN-ION CONCENTRATION OF PROTOZOAN CULTURES

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. .
