Carolina Investigations® for Use with AP® Chemistry: Spectrophotometric Analysis of Color Kit

$26.95
(in stock)

Description

Addresses AP® Chemistry Big Idea 2, Structure and Properties. Introduce students to the mechanics of molecular spectroscopy and how electromagnetic radiation interacts with molecular compounds. Determine the concentration of food dyes in powdered drink mixes using the Beer-Lambert law. Prepare standard solutions of 2 food dyes, plot calibration curves of absorbance as a function of concentration for each dye, then determine the concentration of each dye in its unknown solution. Procedure does not use toxic thiocyanate salts. For 30 students working in pairs.

Note: This lab is written to use 100 test tubes. In Investigation 2, students make 10 serial dilutions. If 100 test tubes are not available, students can make one dilution at a time, follow the lab procedure, then rinse out and reuse their available test tubes.
