| Description |
Soft white metal, silvery when cut but reacts rapidly with
oxygen and vigorously with water. Metal obtained from NaCl + KCl at 1100
K. Used in fertilizers, chemicals, and glass. Diagnostic tests:
In solution, a potassium will give a violet flame test color. This flame test will be contaminated with the colors of the
other alkaline elements which are present in the sample. The test is best
observed through a blue filter to suppress the yellow sodium flame.
