The binding of oxygen by hemoglobin in the blood involves the following equilibrium reaction: HbH+(aq) + O2(aq) ⇌ HbO2(aq) + H+(aq)
In this equation, Hb is hemoglobin. The pH of normal human blood is highly controlled within a range of 7.35 to 7.45. Given
the above equilibrium, why is this important? What would happen
to the oxygen-carrying capacity of hemoglobin if blood became
too acidic (a condition known as acidosis)?
