PRODUCT DESCRIPTION

The amount of vitamin C in the juice from different citrus fruits such as oranges and lemons can be compared in this fun and analytical wet experiment. There are actually three different procedures described; two use a starch-iodine indicator and one uses indophenol. All materials, procedures, and result tables are provided and the science behind the titrations is completely explained.

When students finish they can work on the provided student activity worksheet, answer key included. There is also a page of document camera notes and images on the vitamin C molecule. Simply print and use. Ideas for extension experiments are included.

PS. Students will enjoy squeezing their own fruit juices!
