A buffer solution contains 0.205 M NaHSO3 and 0.405 M K₂SO3. If 0.0321 moles of nitric acid are added to 150 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume change does not change upon adding nitric acid) pH = A buffer solution contains 0.454 M hydrofluoric acid and 0.341 M potassium fluoride. If 0.0305 moles of potassium hydroxide are added to 125 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume does not change upon adding potassium hydroxide.) pH = =
