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 ...

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 ...

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH 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 ...

Sorensen's method of expressing acidity -- the negative logarithm of hydrogen ion concentration (pH) -- still has a wide range of real-world uses Google on Tuesday celebrated Danish chemist Soren ...

Hydrogen-ion concentration (pH) affected the percent germination of weeping lovegrass, sand bluestem, and blue panic in laboratory tests. The latter two species exhibited the ability to germinate over ...
