Question

12 g/L nitrate (NO^-_3) is contaminating an aquifer (groundwater). The starting pH of the water is 3.0. Nitrate is reduced to ammonium (NH^+_4) with acetate (CH_3COO^-) as the electron donor. How much acetate is required to reduce all nitrate? What concentration of protons will be generated that need to buffered from the system? How much zero valent iron (ZVI) would you need to completely reduce the nitrate in the same manner assuming it becomes ferrous iron in solution? Give all answers in mg/L or g/L.
