point at which an indicator changes color is called the end point of the titration. Phenolphthalein is an appropriate choice for this titration. In acidic solution, phenolphthalein is colorless, and in basic solution, it is pink. At the equivalence point, the number of moles of acid equals the number of moles of base.

Instead of sulfuric acid, this lab involves two different acids: citric acid and ascorbic acid (both are acids, thus each reacts with NaOH). You can determine the TOTAL amount of acid (total moles of H moles of H from citric acid moles of H from ascorbic acid) present in a juice sample by titration with NaOH, a strong base. Equation 1

For an acid-base titration, the equivalence point occurs when moles of acid equal moles of base: [H 3O ] [OH-]. Furthermore, the equivalence point will reveal whether the solution consists of a strong or weak acid. For an acid, HA, in solution, the equilibrium constant K a for the process can be determined: HA (aq) H 2O (l) H
