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 ...

The pH of a solution is a measure of its concentration of hydrogen ions. The higher the concentration of H + ions in an acidic solution, the lower the pH. A pH of 1 represents a hydrogen ion ...

Managing soil pH is a crucial but often overlooked aspect of soil health and crop productivity, says Marla Riekman, a land ...

Acidic and alkaline solutions can conduct electricity because they have ions that are free to carry charge. Look at the formulae of these acids. They all contain H + ions.
