Problem- A buffer solution contains 0.382 M ammonium bromide and 0.418 M ammonia.
If 0.0268 moles of perchloric acid are added to 125 ml of this buffer, what is the pH of the resulting solution?
(Assume that the volume change does not change upon adding perchloric acid)
pH =I am in hurry anyone is there provide me the answer in quick phase
