The pH of an arterial blood sample is 7.15. Upon acidification of 10 ml of the plasma 5.91ml of CO2 is produced at standard temperature and presure.

Calculate:
a) total CO2 in the specimen
b) the individual concentration of disolved CO2(H2CO3) and HCO3-
c) The partial pressure of the dissolved CO2 in mm Hg.

*1 mole of CO2 at stp is 22.26L
Pka=6.1 at 37C
Solubility coefecient =0.031 mmol/LmmHg at 37 C
