Do I have this chemistry question correct?
1) How does the carbonic acid-bicarbonate buffer system respond to the addition of an acid to the system? To the addition of a base to the system. One Bonus Point
The carbonic-acid bicarbonate buffer system is expressed as H+ + HCO3- = H2C03 = H20 + CO2
In response to the addition to an acid in the system, in this case carbonic acid, the ph would normally be lowered significantly if it weren’t for the presence of the buffer and the conversion by carbonic anhydrase (enzyme responsbile.) The buffer acts to change carbonic acid into CO2.
If a base is presented, in this case carbon dioxide and dissolved in water it presents excess carbonic acid to which more CO2 is created and released aerobically. The buffering capacity increases as the pH is closest to the desired pH (which for blood is around 7.4)
