Calculate the pH after the following volumes of acid have been added. Correct A strong acid is added to a strong base, so the pH will depend on only the concentration of excession, whether it is OH or H+. At this volume of acid, the hydroxide ion will remain in excess and the concentration can be calculated. [] OH remaining = MOH-initialoconsumed Vital 0.00300 mol-0.00250 mol 0.040 L The pH and pOH sum to 14 at 25°C, so the pH of the solution can be calculated from the hydroxide concentration as follows: pH = 14 + log [OH-] = 14 +log (0.0125) ( Part B 22.0 mL of the acid Express your answer using two decimal places.
