Question- In conducting a titration of 75.00 mL of certain triprotic acid with 0.0800 M NaOH, the following information was recorded:
1) The first equivalence point was observed at pH 4.94 after the addition of 12.40 mL of NaOH.2) The second equivalence point was observed after the addition of 25.00 mL of NaOH (total); the pH was measured to be 7.85
Determine the apparent concentration of this triprotic acid and the dissociation constanct for the first and second proton dissociation step (Ka1 and Ka2), given that pKa3 is 9.54.
