Product Information

Is that concentrated or fresh squeezed?

Vitamin C plays an essential role in the human immune system. It aids in fighting off foreign invaders, is vital to the production of collagen, protects the fat-soluble vitamins A and E from oxidation, aids in neutralizing pollutants, is needed for antibody production and has natural antihistamine properties.

Recent research has shown that it may also contribute to healthy bones and teeth, aid iron absorption, and help maintain cognition in the elderly. Some aquatic hobbyists have even begun using vitamin C in their saltwater and reef tanks. The human body does not produce vitamin C. For this reason we need to get this vitamin from other sources.

In this lab, students first titrate a known standard solution of vitamin C in order to determine its concentration. They then prepare their own samples using common fruits and vegetables (fresh, canned or frozen). By comparing their results to the standard solution, students are able to quantify the amount of vitamin C present in their own samples.

Lab comes with enough materials (except for fruits or vegetables) for 8 lab groups, teacher’s guide, and student study and analysis copymasters.
