10. A wastewater stream containing 1.00 ´ 10-3 M disodium NTA, Na2HT, as the only solute is injected into a limestone (CaCO3) formation through a waste disposal well. After going through this aquifer for some distance and reaching equilibrium, the water is sampled through a sampling well. What is the reaction between NTA species and CaCO3? What is the equilibrium constant for the reaction? What are the equilibrium concentrations of CaT-, HCO3-, and HT2-? (The appropriate constants may be looked up in this chapter.)
