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 ...

SOME years ago Shedlovsky 1,2 suggested that proton transfer reactions could give rise directly to e.m.f., and apparently confirmed this idea by demonstrating that a glass electrode, coated with ...

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 ...
