1. A 0.3178 g sample of potassium hydrogen phthalate is
dissolved in 100 mL of water. If 33.75 mL of sodium hydroxide
solution are required to reach the equivalence point, what is the
molarity of the sodium hydroxide solution?
2. Does the amount of water used to dissolve the KHP standard
affect the calculated molarity of the sodium hydroxide? Explain why
or why not.

A 0.6972 g of impure potassium hydrogen phthalate (FW: 204.23)
was dissolved in 30 mL of water and 2 drops of phenolphthalein was
added. It required 24.83 mL of 0.1097 M NaOH for complete
titration.

(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)
