using a sample of river water sample analyzed for total inorganic carbon ,The river pH= 7.1 and an inorganic C concentration of 6.97 mg C/L. Determine what is the alkalinity of the river water in expressed in mg CaCO3/L? The following reactions can be used to describe this system: CO3 ^2- + H+ ↔ HCO3- Kf1 = 2.13 x 1010; HCO3- + H+ ↔ H2CO3 (aq) Kf2 = 2.22 x 106; Use α expression to determine the specific concentrations of H2CO3, HCO3- and CO3^ 2-at this site.
