The hydrogen ion concentration is a measure of the acidity of seawater and is commonly expressed on the pH scale; the lower the pH, the higher the hydrogen ion concentration and the acidity of ...

WITH reference to Dr. W. R. G. Atkins's interesting communication in NATURE of September 15, may I be allowed to submit the following comments? The importance of the study of hydrogen-ion ...

THE difficulties in the way of determining the hydrogen ion concentration of the interior of plant cells are great and they have retarded any real advance in our knowledge of the operation of hydrogen ...

Take care to use the word 'dilute' correctly. It can be used as an adjective to describe the concentration of a solution (as here), or as a verb to describe the process of adding more water to a ...

The experiments reported in this paper were undertaken to determine the relation of hydrogen-ion concentration to wheat scab. It was desired to find if possible a limiting acidity for seedling ...

1. The rate of growth of Chlorella in highly buffered nutrient solutions is directly influenced by the H-ion concentration when the PH is less than 5.7. The acid limit for growth of this organism in ...
