The standardized NaOH was used to determine the unknown concentration of H3PO4. The standard NaOH concentrtion is 0.126M. The standard sulfuric acid concentration is 0.150M. 3 NaOH(aq) + H3PO4(aq) → Na3PO4(aq) + 3 H2O(l) Three flasks containing 25.00 mL H3PO4 each was titrated with NaOH. The data is below: Titration 1 Titration 2. Titration 3 Starting volume buret 2.62 mL 18.60 mL 1.20mL Buret volume at end 18.46 mL 34.40mL 16.84mL Calculate the concentration of H3PO4.
