Characteristic
Strontium chloride (SrCl2) is a salt of strontium and chloride. It is a typical salt, forming neutral aqueous solutions. Like all compounds of Sr, this salt emits a bright red colour in a flame.
Chemical formula: SrCl2
Molar mass: 158.53 g/mol
Appearance: White crystalline solid
Density 3.052 g/cm3
Melting point: 874 °C (1,605 °F; 1,147 K)
Boiling point: 1,250 °C (2,280 °F; 1,520 K)
Solubility in water: anhydrous: 53.8 g/100 mL (20 °C)
hexahydrate: 106 g/100 mL (0 °C); 206 g/100 mL (40 °C)
Solubility: ethanol: very slightly soluble
acetone: very slightly soluble
ammonia: insoluble
Magnetic susceptibility (χ): −63.0•10−6 cm3/mol
Refractive index (nD):1.650
Application
Strontium chloride is widely used in fireworks for the source of red color. It is also used in dental and biological research. It is the precursor material to other compounds of strontium. It is used to prepare yellow strontium chromate, a corrosion inhibitor for aluminum. It is also employed in glass-making, sea water aquaria, and metallurgy.
