To mitigate CO2 emissions to the atmosphere, some have suggested injecting CO2 into deep ground water. A ground water with initial pH 8.3 and alkalinity 1 102 M will have CO2 injected until the water comes to equilibrium with PCO2 = 10 bar. Before adding the CO2, the ground water behaves as a closed system.

a. What is the total inorganic carbon (CT) of the ground water before CO2 injection?

b. What are the alkalinity, total inorganic carbon (CT), and pH of the ground water after equilibration with the injected PCO2 ?
