WebBicarbonate (HCO3-) can reversibly bind a free hydrogen ion and in doing so acts as a buffer against pH changes (Review Buffer Basics). Importantly, the weak acid form of the bicarbonate buffer (H 2CO3) is rapidly inter-converted by carbonic anhydrase into gaseous CO2 that remains disolved in the extracellular fluid.
