One of the most important blood buffers is the carbonic acid / bicarbonate system (H2CO3 + HCO3-). A. Fill in the following ICE Table for carbonic acid (using x when needed).           [H2CO3] / [H+] / [HCO3-] Initial- 0.500 Change- Equilibrium- B. A good buffer has an equal concentration of weak acid and its conjugate base.
