Scope on Safety: Flame Tests—A Burning Safety Issue

Science Scope—November 2008

Flame-test demonstrations are conducted annually in middle and high school science labs across the country. The purpose of the flame test is to help identify an unknown metal or metalloid ion based on a characteristic color the salt produces in a flame. The emission spectra help the observer distinguish certain elements. Although they can be an effective and exciting learning tool for science teachers to use, they can also present safety hazards. This month's column describes some safer alternatives science teachers can use to conduct flame tests.
