Sodium silie - Wikipedia

Properties Sodium silies are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions.Sodium silies are stable in neutral and alkaline solutions.In acidic solutions, the silie ions react with hydrogen ions to form silicic acids, which tend to decompose into hydrated silicon dioxide gel.
