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 ...

Since the Industrial Revolution in the late 1700s, we have been mining and burning coal, oil and natural gas for energy and transportation. These processes release carbon dioxide (CO 2) into the ...

in 1909 S.P.L Sorenson, a Danish biochemist devised a scale known as pH to represents the H + ion concentration of an aqueous solution. The pH value of any solution is a number that simply represents ...

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 scale ...

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American I remember learning about acids and bases (or ...

Acid/base indicators are described and used to identify substances as acids or bases. Indicators and the pH Scale: Acid/base indicators are described and used to identify substances as acids or bases.

A Korean research team has developed a new energy-harvesting water purification system capable of producing both purified ...

IN this monograph the authors have set out to give a brief account of our present knowledge of the, hydrogen ion concentration of the blood. In the first chapter there is a short but complete ...

RESPIRATORY failure is usually complicated by a rising blood carbon dioxide tension (pCO 2) and, as a consequence, carbonic acid and hydrogen ion concentration increase in the body fluids. Acutely, ...

a dilute solution contains a relatively small amount of dissolved solute in a given volume a concentrated solution contains a relatively large amount of dissolved solute in a given volume Take care to ...
