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. The hydrogen ion concentration of "Solution A" is, WebbWe will calculate the pH of 25 mL of 0.1 M HCl titrated with 0.1 M NaOH. At each point in the titration curve, we will need to determine two quantities, the concentration of H + remaining in the solution, and the volume of the solution. From these, we can calculate the [H +] and, from that, the pH. 1.
