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).

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
