In 2-3 sentences, based on how you created these buffers, explain how they can "buffer" the addition of H+ or OH-.
Buffers are created by combining a weak acid and its conjugate base or a weak base and its conjugate acid. These buffers can resist changes in pH by accepting or donating H+ ions when an acid or base is added. The weak acid or base in the buffer system reacts with the added H+ or OH- ions, preventing a significant change in pH.
