Characteristic
Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula SnCl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot.
Chemical formula:SnCl2
Molar mass：189.60 g/mol (anhydrous);225.63 g/mol (dihydrate)
Appearance：White crystalline solid
Odor：odorless
Density：3.95 g/cm3 (anhydrous);2.71 g/cm3 (dihydrate)
Melting point：247 °C (477 °F; 520 K) (anhydrous);37.7 °C (dihydrate)
Boiling point：623 °C (1,153 °F; 896 K)(decomposes)
Solubility in water：83.9 g/100 ml (0 °C)
Hydrolyses in hot water
Solubility：soluble in ethanol, acetone, ether, Tetrahydrofuran;insoluble in xylene
Magnetic susceptibility (χ)：−69.0·10−6 cm3/mol
Crystal structure：Layer structure
Application
Tin(II) chloride is used as a sensitizing agent in preparing glass and plastic for metalizing. It serves as a potent reducing agent. Other uses of stannous chloride are tin electroplating baths, corrosion inhibitors, polymers, thermoplastic elastomers, soldering flux, antioxidant, tanning agent and pharmaceuticals.
