Calculating Ka from titration curve. We titrated H3PO4 with NaOH. We began with 40.0 mL 0.0970 MH3PO4, titrated with 0.2085 M NaOH. We reached first equivalence at 18.78 mL NaOH titrated, and second equivalence at 38.50 mL titrated. Calculate Ka1 for H3PO4 using the following data obtained from a titration curve: 1) From the initial pH = 1.97 2) From the pH value half way to the first equivalence point = 2.10 Calculate Ka2 for H3PO4 from the following data...
