In addition, any products past the expiry date may have less due to potential decomposition. Students practice scientific communication by reporting their findings in a professional manner.

Lesson Plan: Comparison of Vitamin C in Juice Drinks Mark as Favorite (16 Favorites)
In this lesson, students will use a color-changing indicator called indophenol and a simplified titration method to determine if vitamin C is present in a variety of store-bought juices. The indicator solution will turn from dark blue to colorless once all the indophenol has reacted with vitamin C in the juices. Students will count how many drops of juice it takes to produce this color change in a 5-mL sample of indicator solution. The greater number of drops it takes to cause the color change, the less vitamin C is present in each drop. They will use their data to compare the relative amounts of vitamin C in the juices to a solution prepared from a vitamin C tablet.
