Juice Lab

Testing for Vitamin C Content In Beverages

TITRATION

For the lab, we placed 20 drops of juice (V8 Golden Goddess, Pear Nectar, Apple, Unsweet White Grapefruit, and a Standard Vitamin C Solution) into a test tube, along with 3 drops of starch. We added I2 drop by drop until the color of the solution changed to blue. We then recorded the number of drops it took to turn the solution blue.
