Flame test lab answers
A flame test is a procedure used to test qualitatively for the presence of certain metals in chemical compounds. When the compound to be studied is excited by heating it in a flame, the metal ions will begin to emit light. Based on the emission spectrum of the element, the compound will turn the flame a characteristic color.2.6: Flame test. Page ID. Muhammad Arif Malik. Hampton University, Hampton, VA. A flame test is a complex phenomenon that is not fully explained. In simple words, when a solution of metal salts, e.g., an aqueous solution of metal chlorides is injected into a flame, some of the metal ions may gain electrons and become neutral metal atoms.A positive test for SO 4 2-, therefore, is the observation of a white precipitate when an aqueous BaCl 2 solution is mixed with the aqueous test solution. When placed in a flame many elements give the flame a distinctive color; an effect that can be used to determine both which elements, and how much of each one, is present in a sample.
