What is the vapor pressure of carbon dioxide in the bottle before it is opened (i.e., when it is at equilibrium) assuming no other ions are present besides those related to CO2 and water? If one were to use compressed air (at 400 ppm CO2(g)) to provide carbonation to the rootbeer, what would the pressure of the air need to be to have a pH of 4.3?
