Anhydrous sodium metasilicate
Anhydrous sodium metasilicate (Na2SiO3) is a white, odorless, crystalline solid. It has a melting point of approximately 1088°C
(1990°F) and a density of around 2.61 g/cm³. This compound is highly soluble in water, resulting in an alkaline solution with a pH
typically around 12-13. It is insoluble in alcohol and other organic solvents. The substance exhibits hygroscopic properties, meaning
it can absorb moisture from the air. When dissolved in water, it forms a viscous, syrup-like solution. Anhydrous sodium metasilicate
is stable under normal conditions but can react vigorously with strong acids, releasing heat and producing sodium salts and silicic
acid. It is commonly used in detergents, water treatment, and as a cement additive due to its ability to improve the mechanical
properties of materials.
