Web(4) Calcium bicarbonate in solution is a good buffer system and thus resists change in pH, but it remains in solution only in the presence of a certain amount of free carbon dioxide. Any process which removes carbon dioxide, as does photosynthesis, tends to cause precipitation of calcium carbonate from solution, especially where the bicarbonate ... 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.

WebMar 30, 2010 · Published Mar 30, 2010 Pachinko Register to Comment I understand, at least in theory, the carbonic acid equation (H2O + CO2 H2CO3 H + HCO3), but I'm not understanding how the buffer system works in practice. So, CO2 build-up is associated with acidosis...but CO2 is itself a neutral molecule, correct? Why is it associated w/ acidosis?
