An interesting practical example, I

• Consider the solubility of carbon dioxide

• CO2 + 3H2O = HCO3–1 + H3O+1 + H2O = CO3–2 + 2H3O+1

• Increasing pressure drives CO2 into solution

• i.e., HCO3–1 & CO3–2 are more stable at higher pressures

• Lower temperatures also lead to increase in the solubility of CO2

• HCO3–1 & CO3–2 can attain higher concentrations in colder water
