An interesting practical example, II
Consider the solubility of calcium carbonate
Concentration of carbonate anion (CO3–2) is buffered by the amount of CO2 in solution
Increasing pressure enables sea water to have greater concentrations of HCO3–1 & CO3–2 (the products of the solubility reaction)
CaCO3 is more soluble at higher pressure
Similar effect occurs with decreasing temperature
CaCO3 is more soluble in cool water than in warm water
Altogether, CaCO3 is increasingly soluble at greater depths
