A soda pop has a pH = 3.80 at 25oC. Calculate the pressure of CO2 inside a closed-bottle of this soda pop at 25oC.

Assume only water and CO2 are present and all dissolved CO2 is present as H2CO3.

Ka1 (H2CO3) = 4.3 x 10^-7 and

delta Gf naught (H2CO3 (aq)) = - 623.08 kJ/m

    A soda pop has a pH = 3.80 at 25oC. Calculate the pressure of CO2 inside a closed-bottle of this soda pop at 25oC. Assume only water and CO2 are present and all dissolved CO2 is present as H2CO3. Ka,1(H2CO3) = 4.3 x 10-7 and ΔGfo(H2CO3,aq) = - 623.08 kJ/m Please include all math steps. The answer is Pco2=1.7atm

    Estimate the pH of natural rainwater, assuming the only substance effecting it is the adsorption of CO2 from the atmosphere. Assume the concentration of CO2 is 390 ppm, and the temperature and pressure are 25 "C and 1 atmosphere. Steps. Assume the absorption of CO2 adds only the carbonate system ions so the ionic present must balance, and are due to Ht, OH, HCO3, and CO32. Establish your charges charge balance equation-+'s = -'s i. Assuming the rainfall is slightly...
