Problem 68P
Carbonic acid has a pKa of 6.1 at physiological temperature. Is the carbonic acid/bicarbonate buffer system that maintains the pH of the blood at 7.3 better at neutralizing excess acid or excess base?
ANSWER:
Solution:
Here we will have to explain, carbonic acid/bicarbonate buffer system which has the pH of the blood at 7.3 better at neutralizing excess acid or excess base.
Step 1
Here it has been given that pKa of carbonic acid is 6.1 and its pH 7.3.Carbonic acid has been neutralized by excess acid or excess base can be explain by the help of Henderson -Hasselbalch equation i.e
