| Hazard Information | Back Directory | [Chemical Properties]
White powder.Soluble in molten caustic soda or potash;
converted to sodium hydroxide by water.
| [General Description]
A white granular material. sodium oxide reacts with water to give sodium hydroxide with the evolution of heat. sodium oxide is corrosive to metals and tissue. sodium oxide is used in chemical manufacture. | [Air & Water Reactions]
The oxides of sodium and potassium react with water vigorously and with enough evolution of heat to cause boiling and spattering of hot caustic solution [Chem. Safety Data Sheets SD-9, SD-10, 1947]. | [Reactivity Profile]
sodium oxide reacts as a base. sodium oxide and nitric oxide react vigorously above 100°C [Mellor 2, Supp. 2:629 1961]. | [Health Hazard]
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Fire Hazard]
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | [Hazard]
Caustic and strong irritant when wet with
water.
