The pH of a water sample is measured to be 9.33. The concentration of carbonate (i. e., CO32-) is measured to be 6.0 mg/L. Assume the system is closed to the atmosphere and the temperature is 25 oC. Given that pKa1 and pKa2 of H2CO3 are 6.35 and 10.33, respectively,
a. Calculate the concentrations of bicarbonate and carbonic acid, respectively. Express your answers both in mol/L and mg/L.
b. Calculate the alkalinity of the water both in meq/L and mg/L as CaCO3.
