POTASSIUM THIOCYANATE

ICSC: 1088

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-WHITE HYGROSCOPIC CRYSTALS. Physical dangers Chemical dangers Decomposes on heating. This produces very toxic fumes of sulfur compounds, nitrogen oxides and cyanides. Reacts violently with strong oxidants. Contact with water causes a strong cooling effect.	Formula: KSCN Molecular mass: 97.18 Decomposes at 500°C Melting point: 173°C Density: 1.9 g/cm³ Solubility in water: very good
