Characteristic

Strontium oxalate is a compound with the chemical formula SrC₂O₄. Strontium oxalate can exist either in a hydrated form (SrC₂O₄•nH₂O) or as the acidic salt of strontium oxalate (SrC₂O₄•mH₂C₂O₄•nH₂O).

Chemical formula:SrC₂O₄

Molar mass: 175.64 g/mol

Density: 2.08 g/cm³

Boiling point: Decomposes above 200 °C (392 °F; 473 K)

Solubility in water:Insoluble in water

Application

Strontium oxalate is a good agent for use in pyrotechnics since it decomposes readily with the addition of heat. When it decomposes into strontium oxide, it will produce a red color. Since this reaction produces carbon monoxide, which can undergo a further reduction with magnesium oxide, strontium oxalate is an excellent red color producing agent in the presence of magnesium. If it is not in the presence of magnesium, strontium carbonate has been found to be a better option to produce an even greater effect.
