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. Use the Henderson-Hasselbalch Equation to determine the pH of the buffer if 0.001 mol of acid is added to the buffer with [H2CO3] = [HCO3-] = 0.500 mol. C. How many moles of acid are needed to cause the failure of the buffer (i.e. the pH is lowered by 1 pH unit)?
