CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Sodium fluorosilicate is a fine, white, odorless, powdered solid. Toxic by ingestion, inhalation and skin absorption. Used as a rodenticide. |
|---|---|
| Color/Form | WHITE GRANULAR POWDER |
| Odor | Odorless |
| Taste | Tasteless. |
| Melting Point | Melts at red heat with decomposition. |
| Solubility | SOL IN 150 PARTS COLD, 40 PARTS BOILING WATER; INSOL IN ALCOHOL |
| Density | 2.68 at 68 °F (USCG, 1999) - Denser than water; will sink |
| Decomposition | When heated to decomposition it emits toxic fumes of /hydrogen fluoride/ and Na2O. |
| pH | SOLN IN COLD WATER IS NEUTRAL |
| Refractive Index | INDEX OF REFRACTION: 1.312, 1.309 |
| Other Experimental Properties | Solutions of fluosilicates are sensitive to hydrolysis in alkaline medium. In the presence of acid, fluosilicate solutions release silicon tetrafluoride. The thermal decomposition of fluosilicates takes place with release of gaseous silicon tetrfluoride and formation of the solid fluoride. /Fluosilicates/ |
| Chemical Classes | Metals -> Metals, Inorganic Compounds |
