RHODIUM TRICHLORIDE, TRIHYDRATE

ICSC: 0746

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance RED DELIQUESCENT POWDER. Physical dangers No data. Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). This generates toxic hazard. Reacts violently with iron pentacarbonyl and zinc. This generates explosion hazard.	Formula: RhCl₃ * 3 H₂O / Cl₃Rh * 3 H₂O Molecular mass: 263.3 Decomposes at 100°C Relative density (water = 1): >1 Solubility in water: soluble
