LibreTexts Chemistry: Titration of Fruit Juices

Some citrus fruits taste more sour, and therefore are more acidic, than others. It is the purpose of this experiment to determine the total acidity of orange, lemon, grapefruit, white grape or lime juice. This procedure can be used to determine the total acidity of most natural fruit juices without further preparation.


We recommend this lab for use with honors chemistry or AP chemistry students as the lab requires the completion of a titration.
