Groundwater in a formation rich in gypsum has the following composition: pH = 7.7 [Na+] = 35 mg/L [Ca2+] = 116 mg/L [SO4 2-] = 110 mg/L [Cl-] = 48 mg/L TOTZn = 65 µg/L DIC = 65 mg/L (a) Calculate the alkalinity (meq/L) of the solution. (b) Determine the speciation Zn and Ca in the solution. What are the two most abundant species of each of these elements? (c) The water is pumped to the surface and placed in an open tank, where it is dosed with 5 × 10-4 M HCl and aerated. Determine the pH, DIC (mg/L) and ALK (meq/L) of the
