See baking soda.BIOLOGICAL BUFFERS. The much higher concentration of hydrogen carbonate ion over that of carbonic acid in blood plasma allows the buffer to respond.

This has been associated with the use of sodium hydrogen carbonate (bicarbonate) injected into the plant for pH control, which produced a pH of 10.5 locally.However, when acting as acids, only the most acidic proton will participate in.

Acid Dissociation Constant

The pKa of CO3 2- is 10.33, which means that at a pH of 10.33 both carbonate and bicarbonate are present in equal amounts.
