Hydrogen Ion Concentration in Relation to Ecological Factors

Hydrogen ion concenteration of the root media in relation to transpiration rates

The Composition, Especially the Hydrogen Ion Concentration, of Sea Water in Relation to Marine Organisms

Since the extensive analyses of Forchhammer and Dittmar, the relative concentration of the chief salts in sea water has been accurately known, the differences in the results of different investigators only slightly exceeding the differences in the values of the atomic weights that they used. Omitting regions affected by land drainage and the melting of the polar ice caps, ocean surface salinity...

The Equilibrium between Hemolytic Sensitizer and Red Blood Cells in Relation to the Hydrogen Ion Concentration

1. In a salt-free medium the proportion of the total amount of hemolytic sensitizer present, combined with the homologous cells, reaches a maximum of almost 100 per cent at pH 5.3. On the alkaline side of this point the proportion combined diminishes with the alkalinity and reaches a minimum of approximately 5 per cent at pH 10. On the acid side of pH 5.3 the proportion combined diminishes with...

Absorption of Nutrients and Plant Growth in Relation to Hydrogen Ion Concentration

The absorption of nutrients depends to a large extent on the reaction of the substrate. At maximal growth the intake of salt is at minimum. Different ions are very differently affected. The intake of water is independent of the absorption of salts.
