Which solution would most likely produce a buffer with a ph near 5? Question gave a list of mixtures
the answer was B C5H5N(base) and C5H3NHI(acid)
the reason why I ignored this initially was because I thought a buffer was only formed by the addition of a weak acid and its conjugate base.
These two do not look like conjugates of each other...
can someone explain why this is the answer.
