WebIt's somewhat contradictory to discuss pH as -log[H+], and then say that pH = -3.6 is possible. There is no way you can cram over 1000 moles of hydronium ions into a liter! The -3.6 value only makes sense if you explain that pH = - log (H+ activity), and that it is the deviation of activity from concentration that makes the value -3.6 possible. WebThe other way to know pOH is subtract 14 from pH value. Formula: pH is stated as the negative of the base ten logarithm of the molar concentration of hydrogen ions available in the solution. pH=-log([H +]) pOH=-log([OH-]) Relationship between pH and pOH is. pH+pOH=14.
