Exploring Chemical Reactions with Food Dyes - Student Laboratory Kit
By: The Flinn Staff
Item #: AP7418
With the Exploring Chemical Reactions with Food Dyes Chemistry Laboratory Kit, students test FD&C food dyes with reactants, simulated hard water, and with oxidizing and reducing agents to determine the presence of a chemical reaction.
Dyes color our world and are found in everything from clothing to food. Yet only seven dyes are used to make all of the artificial colors seen in food made in the United States. Food processing is a rigorous undertaking—explore how these dyes may change color under different chemical conditions. Students test four out of the seven FDC food dyes with a series of reactants, including acidic and basic solutions, simulated hard water, and with oxidizing and reducing agents to determine whether or not a chemical reaction takes place. Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to all questions, and all necessary chemicals.
Complete for 30 students working in pairs. Fifteen reusable 24-well reaction plates are recommended and available separately.
