1. First, we need to find the pKa value for the first ionization of phosphoric acid. From the gi

3. At 25 °C, what would the pH at the half-equivalence point be for the first ionization of the triprotic acid phosphoric acid (H3PO4)? (Hint: Look up pKa values on internet and write all three values here before proceeding.) pKa1 - 2.16 pKa2 - 7.21 pKa3 - 12.32
