Product Details

Vitamin C (ascorbic acid) is very important nutritionally. Students will perform tests to determine Vitamin C content in their favorite fruit juices. The microscale procedure uses 2,6-dichlorindophenol, which is an indicator that changes color as it is reduced by ascorbic acid. Students first use a known Vitamin C solution as the standard. Then the amount of Vitamin C in various juices can be determined. Includes complete instructions and all necessary chemicals and pipets. Complete for 24 students working in pairs. Fifteen reusable 24-well reaction plates are required and available separately.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
