following two equilibrium reactions
describing the transfer of CO2 from the
atmosphere to the ocean (KH = 0.034
M/atm), and the dissociation of carbonic
acid (Ka = 4.5 x 10-7 M):
%3D
CO2(g) + H2O(I)
= H2CO3

H2CO3 = H + + HCO3 –
a) Determine the overall reaction.
b) Determine a combined equilibrium
coefficient that describes this over overall
reaction
c) Write the equilibrium expression for this
overall system
d) If the atmospheric concentration of CO2
is 0.000410 atm, what would be the pH of
the ocean water?
