Borax bead test
Explanation:
Another test that can be used to identify colored ions in a specific compound such as salt is called "Borax bead test".
This test involves use of a clear glassy bead of borax that is joined together in a wire loop which is going to be involved in chemical reaction with the salts of certain metals.
This reaction will produce colors that we can use to identify the exact metal ions that are present.
