How does a buffer work?

A. It prevents added acids or bases from dissociating.
B. It bonds with the added H+ or OH- in solution.
C. It forms new conjugate pairs with the added ions.
D. It neutralizes acids or bases by precipitating a salt.

Prevents any major change in your pH

photon336 · Answer

pH = pKA + log[conjugate base/acid]

I'm not too sure if I remember correctly a buffer is made of a weak acid and its salt.

photon336 · Answer

It must keep the pH relatively constant so I think it has to neutralize anything added so it must react with either OH- or H+
