Air & Water Reactions
Soluble in water.
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.
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.
MAGNESIUM CHLORATE is a powerful oxidizer. Explosive reaction with copper(I) sulfide. Incandescent reaction with antimony(III) sulfide, arsenic(III) sulfide, tin(II) sulfide, tin(IV) sulfide. Incompatible with Al, As, C, Cu, MnO2, organic matter, organic acids, P and S. [Lewis, 3rd Ed . 786] . Mixtures with ammonium salts, with powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979. p. 806]. A combination of finely divided aluminum and MAGNESIUM CHLORATE can explode by heat, percussion, or friction [Mellor 2:310. 1946-47].
White deliquescent crystals or powder. Soluble in water and denser than water. Poses a dangerous fire risk when in contact with organic materials or heat. May be irritating to skin, eyes and mucous membranes. Used to make other chemicals.
