In this lab you will be given six unknown samples of metal The value of the flame test is limited by interference from other brighter colors and by ambiguities where certain different metals cause the same flame color. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. For each solution, it is the first element (the metallic element) in the formula that is responsible for the color. Most people probably remember doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours follows. Very nice representation of the different colors that metal ions produce when heated. Interactive periodic table showing names, electrons, and oxidation states.

In flame tests salts that are dissolved in water are evaporated using a hot flame. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got. Explain why? For example, sodium makes the flame turn bright orange â this is the same orange color made by sodium street lamps and many fireworks. This colour originates from the movement of electrons in the metal ion. You dip a metal wire into a solution and put it over the hottest part of the flame. Usually described as a persistent orange, or "intense yellow" (if you're Wikipedia). This one's pretty conclusively called "lilac". The colors are best observed by heating the sample on a loop of platinum wire moistened with HCl. Periodic Table and Chemical Families 36 Terms.
