![To measure the amount of citric acid (C₂H₂O(CO₂H)³) in a certain candy, an analytical chemist dissolves a 23.00 g sample of the candy in 250. mL of water
and titrates this solution to the endpoint with 23.7 mL of 0.400 M sodium hydroxide (NaOH) solution.
The balanced chemical equation for the reaction is:
C_HO(CO,H),(aq) + 3OH (aq) → CHO(CO,) (aq) + 3H,O()
What kind of reaction is this?
If you said this was a precipitation reaction, enter the chemical formula of the
precipitate.
If you said this was an acid-base reaction, enter the chemical formula of the
reactant that is acting as the base.
If you said this was a redox reaction, enter the chemical symbol of the element
that is oxidized.
Calculate the mass percent of C3H₂O(CO₂H), in the sample. Be sure your
answer has the correct number of significant digits.
