Question

Part A In blood plasma, pH is maintained by the carbonic acid-bicarbonate buffer system. How is pH maintained when acid or base is added to the buffer system? Match the words in the left column to the appropriate blanks in the sentences on the right. Reset Help When acid is added to the blood buffer system, the in the blood reacts with the carbonic acid, CO3 bicarbonate, HCO3 bicarbonate, CO,2 carbonic acid, H2 CO3, carbonic acid, HCO3, OH bicarbonate, H2 CO3, from the acid to neutralize it. When base is added to the blood buffer system, the in the blood reacts with the from the base to neutralize it.

Explanation / Answer

blood buffer is an example of bicarbonate, carbonmate buffer system

when acid is added to the blood buffer system, the HCO3- in the bllod reacts with the H3O+ from the acid to neutralise it

when base is added to the blood buffer system, the H2CO3 in the blood reacts with the OH- from the base to neutralise it.
