3. a. Use the Henderson-Hasselbach equation to determine the ratio of HCO3- to H2CO3 in the patient’s blood 10 hours after aspirin ingestion. b. How does this compare to the ratio of HCO3- to H2CO3 in normal blood (indicate value used from the range given in the table). (pKa1=6.35). c. Can the H2CO3/HCO3- system serve as an effective buffer in this patient? Explain

One of the most important buffering systems in the biological realm is the carbonic acid (H2CO3)/carbonate ion (HCO3- ) system that maintains the pH of blood plasma to a relatively constant value. In blood at 37°C, the Ka of carbonic acid is 8x10-8. Suppose that the concentrations of the buffer components in the blood plasma are: [HCO3-] = 0.24 M and [H2CO3] = .12 M. Calculate the pH of blood.

The pH of blood plasma is 7.40. The principal buffer system is HCO3?/H2CO3. Calculate the ratio [HCO3?]/[H2CO3] in blood plasma. (Ka of H2CO3, carbonic acid, is 4.5 × 10?7) Enter your answer in the provided box.
