A wastewater disposal well for carrying various wastes at different times is drilled into a formation of limestone (CaCO3), and the wastewater has time to come to complete equilibrium with the calcium carbonate before leaving the formation through an underground aquifer. Of the following components in the wastewater, the one that would not cause an increase in alkalinity because of either the component itself or its reaction with limestone, is (a) NaOH, (b) CO2, (c) HF, (d) HCl, (e) all of the p
