  1. Substances containing potassium impart a purple color to a flame. (Web site)
  2. This fact is the basis of the flame test for the presence of potassium in a sample.

Mineral Oil

  1. Unlike lithium and sodium however, potassium cannot be stored under oil indefinitely.
  2. Solid potassium reacts violently with water, and should therefore be kept under a mineral oil such as kerosene and handled with care.
  3. Potassium oxidizes very rapidly in air and must be stored under argon or under a suitable mineral oil.
