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.
Generally, water has a pH level of 7 (which is neutral) or 8 on the pH scale of 1-12. Acidic substances have pH levels between 1-6 while alkaline substances have pH levels between 8-12. To give you a better understanding of what substances are acidic and which ones are alkaline, regard the following scale:
