8. Our bodies are able to preserve a near constant pH due to the presence of hydrogen carbonate anion (HCO;"). K values for the diprotic acid carbonic acid (H;CO;) are Kj = 4.5 x 107, K2 = 4.7 x 10-1". a) Hydrogen carbonate anion is an amphoteric species. Define amphoteric. b) In the space below, write out chemical equations to describe the behavior of this species as both a Bronsted acid and a Bronsted base, and use the equilibrium constants given above to decipher whether a solution of HCO;, will be acidic, basic, or neutral. Support your answer with pertinent calculations.

Transcribed Image Text:8. Our bodies are able to preserve a near constant pH due to the presence of hydrogen carbonate anion
(HCO,). K values for the diprotic acid carbonic acid (H,CO;) are Kaj = 4.5 x 10?, K2 = 4.7 x 10-".
a) Hydrogen carbonate anion is an amphoteric species. Define amphoteric.
b) In the space below, write out chemical equations to describe the behavior of this species as both a
Bronsted acid and a Bronsted base, and use the equilibrium constants given above to decipher whether
a solution of HCO;¯ will be acidic, basic, or neutral. Support your answer with pertinent calculations.
