WebBicarbonate-Carbonic Acid Buffer. The bicarbonate-carbonic acid buffer works in a fashion similar to phosphate buffers. The bicarbonate is regulated in the blood by sodium, as are the phosphate ions. When sodium bicarbonate (NaHCO 3), comes into contact with a strong acid, such as HCl, carbonic acid (H 2 CO 3), which is a weak acid, and NaCl ... WebJan 30, 2024 · Human blood contains a buffer of carbonic acid ( H 2 CO 3) and bicarbonate anion ( HCO 3 −) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid. Furthermore, the carbonic acid in the first ...
Webkidney). Carbonic acid is in equilibrium with bicarbonate and there is an apparent pKa = 6.10 for the overall reaction: CO2 + H20 ~ H2CO3 ~ H + + HCO3- (i) Thus, in a closed vessel with no gas phase a CO2/bicarbonate buffer would be an example of (2), above, and would be a poor buffer at pH 7.40.
