| Hazard Information | Back Directory | [Chemical Properties]
White crystals or crystalline powder.
Soluble in water; insoluble in alcohol. | [General Description]
Crystalline solid. Soluble in water and denser than water. Hence sinks in water. Contact may cause irritation to skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals. | [Air & Water Reactions]
Soluble in water. | [Reactivity Profile]
MAGNESIUM BROMATE is an oxidizing agent. May cause ignition in contact with organic materials. A combination of finely divided aluminum with finely divided MAGNESIUM BROMATE can explode by heat, percussion, or friction [Mellor 2:310. 1946-47]. | [Health Hazard]
Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. | [Fire Hazard]
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. 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. | [Hazard]
Dangerous fire risk in contact with organic
materials. | [Description]
Magnesium bromate hexahydrate is a white crystalline
compound that is insoluble in alcohol, but soluble
in water. It reacts with methyl alcohol to form a complex.
It is a fire hazard but is used as an analytical reagent.Magnesium bromate has found little usage in Industry
because there are better oxidizing agents available. It is
offered for sale commercially but in limited quantities. | [Preparation]
Magnesium Bromate can be
prepared by the reaction of bromic acid and magnesium
carbonate:
MgCO3＋ 2HBrO3→Mg(BrO3)2＋ CO2＋H2O
However, magnesium bromate is not stable in an
acidic environment and tends to decompose if one
attempts to remove it from solution. Thus, the best
method of preparation involves the use of sodium
bromate which is basic enough to prevent such decomposition
in solution:
Mg(OH)2＋ 2NaBrO3→Mg(BrO3)2＋ 2NaOH
The product is a hexahydrate, Mg(BrO3)2·6H2O
This salt can also be prepared by adding a solution of
magnesium sulfate to a suspension of barium bromate:
MgSO4 (aq)＋ Ba(BrO3)2 (s)→Mg(BrO3)2 (aq)＋ BaSO4(s)
The solution is then evaporated to recrystallize the
hexahydrate, Mg(BrO3)2·6H2O. |
