WebbThe full form of pH is “ Potential of Hydrogen”. pH is known as the negative logarithm of H + ion concentration. Hence the meaning of the name pH is explained as the strength of hydrogen or power of hydrogen. pH describes the concentration of the hydrogen ions in a solution, which is the indicator of the acidity or basicity of the solution. WebbThe degree of acidity is expressed in terms of pH, which is defined as the negative logarithm of the hydrogen ion activity. Therefore, the pH of a 0.01-molar hydrogen ion solution is pH = −log ( 10−2 mol H+ L) = 2 pH = − log ( 10 − 2 mol H + L) = 2 At pH 7, the concentration of H+ ions and OH- ions are equal, and the soil or solution is neutral.
