Webb23 aug. 2024 · The HH equation tells us that this will depend on the pH and the pKa of the functional group. If the pH is 2 units below the pKa, the HH equation becomes, -2 = log A/HA, or .01 = A/HA. This means that the functional group will be about 99% protonated (with either 0 or +1 charge, depending of the functional group). WebbOne way to start this problem is to use this equation, pH plus pOH is equal to 14.00. And we have the pOH equal to 4.75, so we can plug that into our equation. That gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25.

WebbMathematically, 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 … WebbIn this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H +] , we can solve for [H +] as, − pH = log [H +] , [H +] = 10 −pH, by exponentiating both sides with base 10 to "undo" the common logarithm.
