Human blood contains a buffer of carbonic acid (H 2CO 3) and bicarbonate anion (HCO 3-)...
Human blood contains a buffer of carbonic acid (H 2CO 3) and bicarbonate anion (HCO 3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. Carbonic acid is about 0.108 percent and the density is 1.67 g/mL. Determine the molarity of carbonic acid in blood.
