Carolina ChemKits®: Vitamin C in Fruit Juices

Item # 840994 Exclusive

Determine the concentration of vitamin C in fruit juice quickly and easily in this microscale experiment. Students titrate solutions of known vitamin C concentration and plot a calibration curve. They then titrate their fruit juice and determine the concentration of vitamin C using their calibration curve. Students practice mixing solutions, graphing data, and writing and balancing chemical equations. Fruit juice not provided. Materials are sufficient for 30 students working in teams of 3.

Grades 9–12. Determine the concentration of vitamin C in fruit juice quickly and easily in this microscale experiment. An excellent opportunity to perform an oxidation-reduction titration and learn how chemistry is used to test common products. Students initially titrate known solutions of vitamin C and plot a calibration curve. Students then titrate their fruit juice and determine the concentration of vitamin C using their calibration curve. Because each fruit sample takes just minutes to titrate, students can complete multiple trials in 1 class period. Encourage students to test different types of fruit juices and different brands. Let students test how stable vitamin C is to heat and air using conditions they choose. This experiment gives students practice mixing solutions, performing microscale investigations, graphing data, and writing and balancing chemical equations - including oxidation and reduction half-reactions. Fruit juice not provided. Materials are sufficient for 30 students in teams of 3.
