The chemical formula is : CO2 (carbon dioxide)
Explanation
Carbonic acid is H2CO3 which dissociates
as H2CO3
H+ + HCO3-
The released hydrogen ions decrease the blood pH. To reduce carbonic acid, following reaction takes place in lungs
H2CO3 (aq)
H2O (l) + CO2 (g)
The gaseous carbon dioxide is exhaled from the lungs.

Explain the role of buffers in the control of blood pH Question In the digestive process, acids are introduced to the blood more than bases. The bicarbonate buffer system acts to neutralize pH changes in the blood. The respiratory system is involved in the process to help maintain the levels of carbonic acid in the blood. What compound is exhaled in order to reduce the carbonic acid concentration in the blood? • Give the answer as a chemical formula, ....

In the digestive process, acids are introduced to the blood more than bases. The bicarbonate buffer system acts to neutralize pH changes in the blood. The respiratory system is involved in the process to help maintain the levels of carbonic acid in the blood. What compound is exhaled in order to reduce the carbonic acid concentration in the blood? Give the answer as a chemical formula. Do not include the state (phase).

1. Blood is maintained at a pH of 7.4 by the primary buffers in the plasma and secondary buffers in the erythrocytes. The plasma contains carbonic acid/bicarbonate as one of its primary buffers. The pK for this buffer system is 6.3 H2CO3 <=> H+ + HCO3- What is the ratio of bicarbonate to carbonic acid in normal blood plasma?

Explain the role of buffers in the control of blood pH Question What are the causes of metabolic alkalosis? Select the correct answer below: O Too much CO2 is eliminated, dropping the CO2 pressure below 38 torr and resulting in a rise in blood pH. This can be caused by hyperventilation, fever, excessive exercise, or reactions to certain drugs. O The body eliminates too much acid or produces too much base for the renal system to compensate, resulting in a...

Carbonate buffers are important in regulating the pH of blood at 7.40. If the carbonic acid concentration in a sample of blood is 0.0010 M, determine the bicarbonate ion concentration required to buffer the pH of blood at pH = 7.40. H2CO3(aq) = HCO3- (aq) + H+ (aq) Ka, = 4.3 x 10-7 27 Concentration =

One of the buffers to maintain the pH of blood is the carbonic acid, H_2CO_3, buffer. Carbonic acid is diprotic and it's equilibrium constants are K_a1 = 4.2 times 10^-7 and K_a2= 4.8 times 10^-11. How would you prepare 5.0 L a carbonic acid buffer of a pH of 7.2 from 0.250 M H_2CO_3? You have available NaHCO_3 (MW = 84.0) and Na_2CO_3 (MW = 106).
