Our flame test kit is an inexpensive way to visually determine the identity and presence of a metal or metalloid ion based on the color of the flame when the chemical sample is placed in it.
To perform the test, wet a nichrome wire loop, like an inoculating loop in pure alcohol (not included in this kit), pick up a small sample of one of the chemicals. Place the loop with the chemical in the hottest part of a flame from a burner. Notice the color of the flame when the chemical sample burns.
Note that the wire should be well cleaned by dipping in alcohol between samples so no dust or other impurities interfere with the true color in the test sample flame. Stainless steel spatulas can also be used.
SAFETY: Wear chemical splash goggles and a lab chemical apron. Youths should perform this activity under supervision.
STORAGE OF CHEMICALS: Some of these chemicals are hygroscopic, meaning they will absorb moisture from the air. Keep cap well sealed when not in use. If a chemical becomes slushy, store it in a sealed container with some desiccant, such as a silica gel packet, to remove the excess moisture.
ANOTHER OPTION: You can also demonstrate flame colors by making a small pile of one of the chemicals and wetting it with flammable alcohol. Igniting the alcohol will burn the chemical and show its characteristic flame color.
To test an unknown mineral, compare its observed flame color with the known values from such as the list below:
| Flame Color | Chemical (kit contains 10 grams each) |
| RED | Strontium Chloride Get SDS |
| YELLOW | Sodium Carbonate Get MSDS |
| GREEN | Cupric Sulfate Get SDS |
| VIOLET | Potassium Chloride Get SDS |
| BLUE | Cupric Chloride Get SDS |
DEFINITIONS:
- “SALTS” – Above chemicals are categorized chemically as salts, ionic compounds produced by reacting an acid with a base.
- METALOID ION – Resembles a metal; a non-metal which can combine with a metal to form an alloy.
