1) why is CO2 the conjugate acid of bicarbonate? Please
explaing
CO2 (g) + H2O(l) ⇄
H2CO3 (aq)
2) Exercise increases metabolism and thus increase the amount of
CO2 in the blood. Following a bout of intense exercise,
the pH of your blood was found to be 7.1 and the
HCO3− concentration in the blood to be 8 mM.
Remember the overall reaction for the bicarbonate buffering system
in the blood can be written as:
H2CO3 (aq) ⇄ HCO3- (aq)
+ H+ (aq) ⇄ CO32- (aq) +
2H+ (aq) If the pKa for HCO3−HCO3−is
6.1, what is the concentration of CO2CO2in your blood? Please
enter your answer in mM using one sig. fig. Correct
answer: 8E-1
(how did they calculate this number?)

1)Intense exercise causes acidosis. Their blood pH is 7.1. Knowing that [CO2] is roughly comparable to [H2CO3], what is the[CO2] of their blood if the [HCO-3] = 10mM? (pKa of carbonic acid (H2CO3) is 6.1) 2)Alkalosis is when the pH of the blood rises to > 7.45. It is often causes due to prolonged vomiting, side effect of diuretics, or hyperventilation. It can cause muscle tremors and dizziness. What is the concentration of [HCO-3] assuming that [CO2] is comparable to...

4. It has been shown that aspirin acts directly on the nervous
system to stimulate respiration. Thus, our patient is
hyperventilating due to her aspirin overdose.
b. Explain how aspirin-induced hyperventilation causes the pH of
the patient’s blood to increase. (Hint: what acid/base pair is the
blood’s main buffering system?

Uncompensated Acid/Base Imbalance
Case 1
Mrs. Benette, a 71 year old woman, is brought in by ambulance to
the ED. She is very tired and lethargic but can communicate. She is
complaining of tinnitus (ringing in her ears) that she describes as
a freight train driving by her head and severe dyspepsia (upset
stomach). She has a medical history of rheumatoid arthritis. Upon
questioning of the patient, she tells you she is taking pain
medication for her arthritis but can’t...
