Why are alkali metals stored under oil?
Quick Answer
They are stored under oil to keep them away from air and water. Alkali metals react quickly with both, sometimes dangerously.
The Full Story
Lithium, sodium, and potassium are alkali metals in Group 1, and their single outer electron makes them highly reactive. If left exposed, they can react with moisture in the air or with water vapor on the surface, producing heat and corrosive products. Storing them under mineral oil or another inert liquid prevents contact with oxygen and water. This simple precaution helps keep the metals from tarnishing, oxidizing, or igniting.
Key Facts
1.Lithium, sodium, and potassium are Group 1 metals
2.They have one valence electron
3.Mineral oil blocks contact with oxygen and water
