Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved Carbon dioxide .
Dissolved Carbon dioxide satisfies the equilibrium equation. The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved Carbon dioxide .
K = 0.032M / atm
For a Carbon dioxide partial pressure of 2.4 × 10^-4 atm
in the atmosphere, what is the pH of water in equilibrium with the atmosphere?
