Question- Blood pH lies within the narrow range 7.35 - 7.45. The principle buffer mechanism is shown as the biocarbonate/carbonic acid equilibrium:
H2CO3 ---> H+ + HCO3-
Under the conditions in blood plasma Ka for H2CO3 is 8 x 10^-7. Using this figure, calculate normal blood pH when [H2CO3] is 0.00135 and [HCO31-] is 0.027
