Sodium bromate Chemical Properties,Uses,Production

Chemical Properties

White crystals or powder; odorless. Soluble in water; insoluble in alcohol.

Chemical Properties

Sodium bromate is a colorless or white crystalline solid. Odorless.


The bromates of chief industrial interest are those of sodium and potassium. Sodium bromate is used in mixtures with sodium bromide to extract gold from ore. It is also used as an analytical reagent, as a cleaning agent for boilers, and as a component in hair-waving formulations. Potassium bromate is used primarily as a conditioner for flour and dough; some of its nonfood uses include use as an oxidizing agent for analytic chemistry and as a brominating agent. The bromates of calcium and barium have limited use as oxidizers, maturing agents in flour, and analytic reagents.


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


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

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].


Oxidizing material, dangerous fire risk near organic materials. Toxic by ingestion.

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.

Safety Profile

Poison by ingestion, intravenous, subcutaneous, and intraperitoneal routes. A powerful oxidizer. Violent reactions with Al, As, C, Cu, oil, F2, metal sulfides, organic matter, P, S. lxtures with grease are shock-sensitive explosives at 120’C. When heated to decomposition it emits toxic fumes of Na2O and Br-. See also BROMATES.

Potential Exposure

Used for research and development; as an analytical reagent; for separating gold from ores; making vat dyes; boiler cleaning.


UN1494 Sodium bromate, Hazard Class: 5.1; Labels: 5.1-Oxidizer. UN1450 Bromates, inorganic, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, Technical Name Required.

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.]


Dust may form explosive mixture with air. A strong oxidizer capable of increasing the intensity of an existing fire. Can react, possibly violently, with combustible, organic, or other oxidizable materials, alcohols, glycols, reducing agents, strong acids, finely divided metals, especially aluminum. Contamination with carbon, organic matter, and finely divided metal can cause sodium bromate become shock-sensitive. Decomposes at 381C. Sodium bromate may explode in heat of fire.

Waste Disposal

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
