Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved co2. dissolved co2 satisfies the equilibrium equation.
co2(g) < > co2(aq) the acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved co2. k=0.032 m/atm
for a co2 partial pressure of 4.4×10-4 atm in the atmosphere, what is the ph of water in equilibrium with the atmosphere?
note: since carbonic acid is primarily dissolved co2, the concentration of h2co3 can be taken as equal to that of dissolved co2.
my online homework is due tonight and i am hopelessly lost on how to solve this problem. : (
