The soil pH is a measure of the acidity or alkalinity in soils. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions (H+. or, more precisely, H. 3O+. aq) in a solution. In water, it normally ranges from -1 to 14, with 7 being neutral. A pH below 7 is acidic and above 7 is alkaline.
Acids are primary contributors to the measure of pH in a solution, and the presence of acids a key characteristic of almost all solutions, from blood in the body to foods and drinks we consume. Let's discuss what an acid is and how it affects the pH of solutions when added. How Acids Work. The pH scale is a scale that is used to represent the level of acidity in a solution. A solution with a pH of 7 is neutral, while a solution with a pH below 7 is an acid, and a solution with a pH above 7 is a base. An acid dissociates, or breaks apart, and donates protons, or hydrogen ions, in an aqueous solution, while a base donates hydroxide ions in a solution. Water, for example, is neutral with a pH of 7.
