Hydrogen-ion Sentence Examples

The result of this is that the alkalinity of the sea-water increases and the hydrogen-ion concentration decreases.

Experiments made by Moore and Whitley at Port Erin in the Isle of Man show that the hydrogen-ion concentration falls from about 1084 in Dec. to about 108 ' 4 in April.

Evaporation of the water and anything that lowers the hydrogen-ion concentration have the same effect.

The subject was pursued by Thomson and the Cambridge physicists with great mathematical and experimental ability, and finally the conclusion was reached that in a high vacuum tube the electric charge is carried by particles which have a mass only a fraction, as above mentioned, of that of the hydrogen atom, but which carry a charge equal to the unit electric charge of the hydrogen ion as found by electrochemical researches.

Removal by reacting with ammonia The most likely basic substance which a hydrogen ion is going to collide with is an ammonia molecule.

An ammonia molecule removes a hydrogen ion from the -NH 3 + group in a reversible reaction.

The pH scale is the negative logarithm of the hydrogen ion content of water.

Characteristic changes in extracellular potassium, sodium and hydrogen ion concentrations are usually diagnostic.

Pure water, then, has a hydrogen-ion concentration of io 7 but sea-water gives (because of the mixture of the salts in solution) the concentration 108 ' 2 and when photosynthesis by the larger alga, or diatoms, is very active this figure falls to about 109 ' 1.

Thomson, the successor of Maxwell and Lord Rayleigh in the Cavendish chair of physics in the university of Cambridge, began about the year 1899 a remarkable series of investigations on the cathode discharge, which finally enabled him to make a measurement of the ratio of the electric charge to the mass of the particles of matter projected from the cathode, and to show that this electric charge was identical with the atomic electric charge carried by a hydrogen ion in the act of electrolysis, but that the mass of the cathode particles, or " corpuscles " as he called them, was far less, viz.
