WebbA solution is basic, if the OH - ions are in excess. Definition of pH, pOH, and pKw: The concentrations of hydrogen ions and indirectly hydroxide ions are given by a pH number. pH is defined as the negative logarithm of the hydrogen ion concentration. The equation is: pH = - log [H +] similarly, pOH = - log [OH -] and p Kw = - log [Kw] . WebbThe pH of a solution is therefore defined as shown here, where [H 3 O +] is the molar concentration of hydronium ion in the solution: pH = −log [ H 3 O +] Rearranging this …

WebbTo calculate pH, you should know the concentration of hydrogen ions (H +) in your solution. From there, the pH can be found by: p H = − log 10 ( [ H +]) Since this is a logarithmic calculation, in order to change the pH by one unit (say, from 2 to 3), the concentration of H + must be changed by 10 times (say, from 0.01 mol/L to 0.001 mol/L).
