IT has been found possible to concentrate inorganic ions from aqueous solutions, even if very dilute, by a flotation technique. The principle depends upon the use, as a collector, of a surfactant ...

The ion current also gives a measure of the ion concentration. However, while both modalities are possible, until now no-one has successfully retrieved both types of data simultaneously.

A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, the gradiant causes H-ion diffusion to the surface, where they capture electrons (reduction) to become ...

The pH is a negative logarithmic scale, which measures the molar concentration of hydrogen ions from 1 to 10 14 ions. It therefore has no unit of measurement. Numbers on a negative logarithmic ...

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 ...

Even a minor change of the ions concentration in the cell can dramatically affect biochemical reactions. Recently, scientists from the Institute of Physical Chemistry, ...

The minimum point in the curve varied from about pH 5.5 to pH 6.0. This is similar to the results of Webb (13) in his work on spore germination and hydrogen-ion concentration. The use of various ...
