Product Highlights
This demonstration explores the phenomenon of flame tests used in identifying certain metals by burning their salt compounds in a flame and observing their characteristic colors. Students learn the fundamentals of emission spectroscopy as they observe the colorful flames of 6 metallic salts. This leads to understanding the concepts of electron excitation of atoms and quantum theory.
