  Lesson Plan: Comparison of Vitamin C in Juice Drinks Mark as Favorite (6 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.

  pH, Indicators | Middle School, High School

  Animation: The pH Scale Animation Mark as Favorite (11 Favorites)

  This animation explores the fundamentals of the pH scale and how it is used to distinguish between acids and bases. Students will see everyday examples of acids and bases and where they fall on the pH scale. The logarithmic nature of the pH scale is explained, and universal indicator is introduced as a way of identifying the pH of a substance. There is also a brief overview of the chemistry of acids and bases. This animation was featured in the November 2021 issue of Chemistry Solutions. **This video has no audio**
