A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. Ibd chemistry - flame test practical aim: to test and observe the colour(s) emitted by various metal salts when placed and heated in a bunsen burner. To become familiar with the transfer of energy in the form of quantum, students perform flame tests, which is one way chemical engineers identify elements by observing the color emitted when placed in a flame after calculating and then preparing specific molarity solutions of strontium. The chemistry of an element strongly depends on the arrangement of its electrons pre-laboratory questions and exercises due before lab begins microsoft word - exp_3_flame_tests_configurationdoc author.
