Ever wonder what causes the unusual colors sometimes seen in a fire?
With this kit students can observe the spectra of some fairly common elements by placing the metallic salts in a flame. The kit contains a nichrome wire that is attached to an aluminum handle. By moistening this wire and then dipping it into one of the salts, the characteristic color of the light for each element can be determined when it is then inserted into a colorless Bunsen Burner flame.
This kit also comes with a Pyrex test tube 12.5cm in length. The test tube provides an alternative method to see the spectra of the element. The test tube may be partially filled with water and the outside then dipped in a concentrated solution of the salt for introduction into the flame. Included are salts of barium, boron, calcium, lithium, potassium and strontium. All are in .5oz bottles. Instructions for carrying out the experiment and carrying case are included.
