SODIUM
(Na)
MATERIAL
OVERVIEW
Characteristics:
Soft, silver-white solid, oxidizing rapidly in air;
waxlike at room temperature, brittle at low
temperatures. Store in airtight containers or in
naphtha or similar liquid that does not contain water
or free oxygen. Decomposes water on contact, with
evolution of hydrogen to form sodium hydroxide;
insoluble in benzene, kerosene, and naphtha. Has
excellent electrical conductivity and high
heat-absorbing capacity.
Hazards:
Strong, caustic irritant to tissue. Severe fire risk
in contact with water in any form. Ignites
spontaneously in dry air when heated. To extinguish
fires, use dry soda ash, salt, or lime.
