Do buffers resist change in ph? | Yahoo Answers

13-05-2011· There are no sponges involved. A buffer works because of LeChatelier's principle and a chemical equilibrium between a weak acid and its conjugate base, the components of a buffer. The conjugate base reacts with H+, and the weak acid reacts with OH-. The resulting shift in the position of the equilibrium prevents the pH from changing very much.
