If an infinite atmosphere fixes or holds "dissolved CO2" at 1.00E-5M, what is the pH? Report your result to the nearest tenth of a pH unit. (Compare part of example 2-13, p.60; also compare the first question on this quiz; "dissolved CO2" is actually the sum of CO2 and H2CO3, as noted in the previous question) • Assume • The mixture was formed from pure water and CO2(g) o The mixture remains in contact with the gas phase CO2, so the "dissolved CO2" does not vary from 1.00E-5M • Use opka=6.38 for the first dissociation constant of "dissolved CO2" at 20C; see reaction below o "dissolved CO2" 4 H+(aq) + HCO3-(aq) o Neglect the second dissociation reaction and its equilibrium constant (neither of which are not provided here) o As in the first question on this quiz, H+ and HCO3- can only be formed from "dissolved" CO2, so their concentrations must be equal.
