15PRACTICE PROBLEM
Phosphoric acid (H3PO4) and (NaOH) react according to the following equation:
H3PO4(aq) + NaOH(aq) → H2O(l) + Na3PO4(aq) [unbalanced]
A 0.150 M NaOH solution was used to titrate a 20.00 mL H3PO4 solution with an unknown concentration. If 21.54 mL of NaOH solution was used to reach the equivalence point, determine the concentration of the H3PO4 solution.
