(13) Hydrogen phthalate ion, HC8H4O4–, from potassium hydrogen phthalate (abbreviated as “KHP”; formula = KHC8H4O4), is a weak acid. In an acid-base titration, a 50.0-mL solution of 0.100 M “KHP” solution is titrated with NaOH solution of unknown concentration. The following net ionic equation represents the reaction that occurs during titration: HC8H4O4–(aq) + OH– (aq) → C8H4O42–(aq) + H2O(l)    (a) If the titration requires 34.0 mL of NaOH solution to reach equivalent point, calculate the molar concentration of NaOH...
