Standard Specification:
Sn Percentage : 54.00% Min
Assay : 99.90 % Min
Stannous sulfate is an inorganic compound containing tin in the +2 oxidation state (stannous ion, Sn²⁺) and the sulfate ion (SO₄²⁻). It’s typically encountered as a white or light-colored crystalline solid and is used in various industrial applications, like electroplating and anodizing.
Properties of Stannous Sulfate
-
Chemical Formula: SnSO₄
-
Molar Mass: Approximately 214.77 g/mol
-
Appearance: White or off-white crystalline powder or solid
-
Solubility:
-
Soluble in water (around 35 g/100 mL at 20°C), but hydrolysis occurs in neutral or basic solutions, forming insoluble tin(II) hydroxide or related compounds.
-
Insoluble in ethanol and most organic solvents.
-
-
Melting Point: Decomposes before melting, typically around 360°C, releasing sulfur trioxide (SO₃) and forming tin oxides.
-
Density: About 4.15 g/cm³
-
Oxidation State: Tin is in the +2 state, making it a reducing agent. It can oxidize to Sn⁴⁺ (stannic form) when exposed to air or oxidizing agents.
-
Reactivity:
-
Acts as a reducing agent in chemical reactions.
-
Sensitive to air and moisture, where it may slowly oxidize or hydrolyze.
-
Stannous sulfate solution is mainly used for coloring aluminum profiles by an anodizing process in the building industry. Stannous sulfate is also used in electroplating, for electrolytic tin plating..
