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

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
