Q

What is the carbonic acid bicarbonate system?

A

Carbonic acid (H2CO3) can act as a weak acid and bicarbonate ion (HCO3-) this buffer system compensates for either an excess or shortage of H+

Q

If there is an excess H+ (acidic condition)

A

The HCO3- can function as a weak base removing the excess H+ and HCO3- = H2CO3 (carbonic acid)

Q

If there is a shortage of H+ (alkaline condition)

A

H2CO3 can function as a weak acid and provide the needed H+ H2CO3 = H+ and HCO3- (bicarbonate ion)
