CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Fluorophosphoric acid, anhydrous appears as a colorless liquid. Corrosive to metals and tissue. Used in metal cleaning, as a chemical polishing agent and as a catalyst. |
|---|---|
| Color/Form | COLORLESS LIQUID |
| Odor | Practically no odor |
| Solubility | SOL IN ALL PROPORTIONS IN COLD WATER |
| Density | 1.818 @ 25 °C/4 °C |
| Vapor Density | 3.45 |
| Viscosity | VISCOUS LIQUID |
| Corrosivity | Corrosive to glass since HF is present in the aqueous acid and can be generated by hydrolysis of the anhydrous acid. |
| Dissociation Constants | pK1 = 5.5; pK2 = 8.5 |
| Other Experimental Properties | Hydrolyzes when diluted with water producing phosphoric acid. |
| Chemical Classes | Other Classes -> Fluorides, Inorganic |
