(CH,O(CO,H),)' To measure the amount of citric acid in a certain candy, an analytical chemist dissolves a 22.0 g sample of the candy in 150. mL of water and titrates this solution to the endpoint with 30.9 mL of 0.3100M sodium hydroxide (NaOH) solution. The balanced chemical'equation for the reaction is: C,H,0(CO,H), (aq) + ЗОН (ад) CH,0(CO.), (aq) + 3H,0 () O precipitation What kind of reaction is this? O acid-base O redox X. 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 C,H,O(CO,H) in the sample. Be sure your answer has 3 significant digits.
