CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Hexafluorophosphoric acid appears as a clear colorless aqueous solution containing 60 percent hydrogen hexafluorophosphate (HPF6) by mass. Density 1.65 g / cm3. Corrosive to metals and tissue. |
|---|---|
| Color/Form | Colorless liquid. The commercial product may have a dark honey color which is thought to be due to reduced phosphate species. |
| Melting Point | MP: 31 °C (6H2O) /Hexahydrate/ |
| Stability/Shelf Life | STABLE IN NEUTRAL AND ALKALINE SOLN /65% SOLN/ |
| Decomposition | WHEN HEATED TO DECOMP, IT EMITS HIGHLY TOXIC FUMES OF /HYDROGEN FLUORIDE/ AND PHOSPHOXIDES. |
| Corrosivity | Corrosive to glass since HF is present in the aqueous acid and can be generated by hydrolysis of the anhydrous acid. |
| Other Experimental Properties | Specific gravity: 1.81 /65% soln/ |
| Chemical Classes | Other Classes -> Fluorides, Inorganic |
