CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Sodium silicate appears as a powdered or flaked solid substance. Strong irritant to skin, eyes, and mucous membranes. May be toxic by ingestion. Concentrated aqueous solutions used as a glue. |
|---|---|
| Color/Form | COLORLESS TO WHITE OR GRAYISH-WHITE, CRYSTAL-LIKE PIECES OR LUMPS |
| Solubility | In commerce mole ratios of SiO2 to Na2O vary from 1.5 to 3.3. ... The higher the ratio (e.g., the less sodium) the lower the solubility and alkalinity. |
| Density | 1.1 to 1.7 at 68 °F (USCG, 1999) |
| Autoignition Temperature | Not flammable (USCG, 1999) |
| pH | AQ SOLN ARE STRONGLY ALKALINE |
| Other Experimental Properties | COAGULATED BY BRINE; PRECIPITATED BY ALKALINE EARTH & HEAVY METAL IONS |
| Chemical Classes | Other Classes -> Salts, Basic |
