Sodium bromate Chemical Properties,Uses,Production

Chemical Properties

white crystals

Definition

ChEBI: An inorganic sodium salt having bromate as the counterion.

Uses

As a mixture with sodium bromide for dissolving gold from its ores.

General Description

A white crystalline solid. May explode under prolonged exposure to heat or fire. Used in chemical analysis.

Air & Water Reactions

Water soluble.

Reactivity Profile

Sodium bromate is an oxidizing agent. May react violently with combustibles and reducing agents. Reacts with textiles, oil, fat, grease, sugar, sawdust and ammonium salts, carbon, phosphorus, metal powders and sulfides with hazard of fire and explosion [Handling Chemicals Safely 1980 p. 831]. A mixture of finely divided aluminum with finely divided Sodium bromate explodes by heat, percussion, and friction [Mellor 2:310 1946-47].

Health Hazard

Toxic by ingestion. Inhalation of dust is toxic. Fire may produce irritating, corrosive and/or toxic gases. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

These substances will accelerate burning when involved in a fire. May explode from heat or contamination. Some may burn rapidly. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Purification Methods

It is crystallised from hot water (1.1mL/g) to decrease contamination by NaBr, bromine and hypobromite. [Noszticzius et al. J Am Chem Soc 107 2314 1985.]
