In flame test compounds of some metals, in presence of conc. It's possible to get a vivid hot pink color, although more muted colors are also possible. Flame Test Lab Activity Key Note: If chloride compounds are not available, metal nitrate compounds may be substituted. For example, sodium makes the flame turn bright orange – this is the same orange color made by sodium street lamps and many fireworks. Other elements that can impart a blue color to a flame test are zinc, selenium, antimony, arsenic, lead, and indium. Flame tests help us produce colors of metallic ions. The heat from fire is dependent on the type of fuel being burned and the chemical reaction that is taking place as a result as the fuel reacts with oxygen. When metal salts (ionic compounds) are heated in a Bunsen burner flame, the metal gives off a characteristic color. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. Most fuels contain sodium (e.g., candles and wood), so you're familiar with the yellow color this metal adds to a flame.
