The pH of a water is measured to be 7.5. The system is open to atmosphere and the temperature is 25 oC. Assume that the system is in equilibrium with atmosphere, calculate the concentrations of carbonic acid, bicarbonate, carbonate, and CT (total carbonates). (given pKa1 and pKa2 of H2CO3 are 6.35 and 10.33, respectively).
