---|---|---|---|
Molecular Formula: | Na | CAS No: | 7440-23-5 |
EINECS: | 231-132-9 | Size: | Customized |
High Light: | high purity materials,pure metal |
Appearance: silver white, light, soft and ductile metal, lighter than water and waxy at normal temperature. At ambient temperature, the surface is rapidly oxidized, and the hydrogen and sodium hydroxide are released from the strong reaction of water or tidal force, resulting in a large amount of heat release, causing combustion or explosion. It can react with halogen and other inorganic substances and organic compounds in varying degrees.
Properties: silver white, light, soft and malleable metal, is lighter than water, when the temperature of wax.
