Chemical Properties
Green crystalline powder or crystals
General Description
Chromic fluoride solution is a green crystalline solid dissolved in water. CHROMIC FLUORIDE, SOLUTION(7788-97-8) is corrosive to metals and tissue.
Reactivity Profile
Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas.
Air & Water Reactions
Water soluble.
Hazard
Irritant to skin and eyes, especially in solution.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Physical properties
Dark green needles (anhydrous salt) or green hexagonal crystals (trihydrate); density 3.8 g/cm3 (anhydrous fluoride), 2.2 g/cm3 (trihydrate); anhydrous salt melts at 1,100°C and sublimes above this temperature; practically insoluble in water and ethanol (anhydrous salt); trihydrate sparingly soluble in water; soluble in HCl forming a violet solution.
