A 1 liter solution contains 0.357 M hydrofluoric acid and 0.268 M potassium fluoride. Addition of 0.295 moles of hydrobromic acid will: (Assume that the volume does not change upon the addition of hydrobromic acid.) O Raise the pH slightly O Lower the pH slightly O Raise the pH by several units O Lower the pH by several units O Not change the pH O Exceed the buffer capacity
