SOLVED: 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:When acid is added to the blood buffer system, the OH- in the blood reacts with the bicarbonate, HCO3-, from the acid to neutralize it.When base is added to the blood buffer system, the H in the blood reacts with the carbonic acid, H2CO3, from the b
