3 cards from this section. Quick, good the night before a test.
What are the components of an acidic buffer?
Think about combinations like acetic acid and its salt.
Why do buffer solutions resist pH changes?
Consider how acids and bases react to form weaker species.
What is the primary function of a buffer solution?
Consider the context of shared proton reactions.
True or False: All buffer solutions have a strong acid and a strong base.
Recall the definition of a buffer.
Calculate the pH of a buffer solution containing 0.1 M acetic acid and 0.1 M sodium acetate, where pKa = 4.76.
What happens when concentrations are equal?
Design a buffer system that works at a pH of 7.4. Specify the weak acid and its conjugate base.
Consider biological systems and their buffers.
