| White, odorless, crystalline powder. D 3.0. Slightly soluble in water; soluble in hydrochlo- ric acid. | |
| Potassium fluorosilicate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. | |
| Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. | |
| Potassium fluorosilicate is a white to yellowish powder, poorly soluble in water (0.68% at 20 degree ). Because of its poor solubility, it is not commonly used as a modifying reagent. | |
| A poison by ingestion and subcutaneous routes. Ingestion can cause vomiting and dtarrhea. A strong irritant. Incompatible with hydrofluoric acid. When heated to decomposition it emits toxic fumes of SiF4, K3SiF7, and KF. | |
| Crystallise it several times from conductivity water (100mL/g) between 100o and 0o. |
