Ph is negative logarithm of
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. Webb7 apr. 2024 · The range of a pH scale is from 0 to 14. Anything below 7 on the pH scale is acidic. Anything above 7 on the pH scale and below 14 is basic in nature. The value if it is at exact 7, then it is known as neutral. pH means the strength of hydrogen in a solution. pH is defined as the negative logarithm of base 10 in Hydrogen ions.
