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 1x10-2m will have co2 injected until the groundwater comes to equilibrium with pco2=10 bar. before adding the co2, the groundwater behaves as a closed system. you can assume that activities are equal to concentrations. (a) what is the total inorganic carbon (ct) of the groundwater before co2 injection. (b) what are the alkalinity, total inorganic carbon (ct) and ph of the groundwater after equilibration with the injected pco2?

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is
