WebbNote 1: The amount of CaCO 3 required will depend on the components of the soil substrate including food, and should be determined by measurements of soil sub-samples immediately before the test. pH is measured in a mixed sample in a 1 M solution of potassium chloride (KCl) or a 0.01 M solution of calcium chloride (CaCl2) (13). WebbThe pH of a solution is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH +. [15] Mathematically, pH is expressed as: For example, for a solution with a hydrogen ion activity of 5×10 −6 (i.e., the concentration of hydrogen ions in moles per litre), the pH of the solution can be calculated as follows:
