Question
To mitigate CO2 emissions to the atmosphere, some have suggested injecting CO2 into deep groundwater. A groundwater initially at pH 8.3 with an alkalinity of 1*10^2 M will have CO2 injected until the groundwater comes to equilibrium with P(CO2)=10 bar. Before adding the CO2, the groundwater behaves as a closed system.
(a) What is the total inorganic carbon (C(T)) of the ground water before CO2 injection?
(b) What are the alkalinity, total inorganic Carbon ((C(T)), an pH of the groundwater after equilibration with the injected P(CO2)?
