(All sizes packaged under mineral oil
in plastic bottles, and then in a metal
can for safer storage.)
HAZARD ALERT: A flammable, corrosive solid; dangerous when exposed
to heat or flame; dangerous by reaction with moist air, water or any oxidizer.
Spontaneously flammable when heated in air; reacts violently with water,
producing very dangerous hydrogen gas and a solution of corrosive sodium
hydroxide.
Storage: Inorganic #1 under dry mineral oil and inside a Flinn Saf-Stor™ Can.
Sodium metal must always be stored under dry mineral oil to prevent contact
with moist air.
Disposal: #3
Shelf Life: Good, if stored safely.
Color and Odor: New material: metallic gray. Old material: white gray. Metal
itself is odorless but is usually stored under an oil or kerosene, either of which
may have an odor.
CAS No. 7440-23-5
*These two packages contain small, precut pieces of sodium for demonstrations.
Technical Note: As you handle sodium be particularly attentive to the use
of dry utensils and an entirely dry work surface. Use all appropriate personal
safety apparel (e.g., gloves, apron, face shield). Sodium would be the better
choice to demonstrate the characteristics of an alkali metal than potassium.
Potassium may develop potentially explosive peroxides.
