The pH of human blood is steady at a value of approximately 7.4 owing to the following equilibrium reactions: CO2(aq)+H2O(l)H2CO3(aq)H2CO3(aq)+H+(aq) Acids formed during normal cellular respiration react with the HCO3 to form carbonic acid, which is in equilibrium with CO2(aq) and H2O(l). During vigorous exercise, a persons H2CO3 blood levels were 26.3 mM whereas his CO2 levels were 1.63 mM. On resting, the H2CO3 levels declined to 24.9 mM. What was the CO2 blood level at rest?
