Sodium silicate (Na4SiO4)

Description:
Sodium silicate, commonly referred to as water glass or liquid glass, is a chemical compound with the formula Na4SiO4. It is a colorless, viscous liquid or a solid glassy substance that is soluble in water, forming an alkaline solution. Sodium silicate is characterized by its high pH, typically ranging from 11 to 13, making it a strong alkaline material. It is known for its adhesive properties and is widely used in various applications, including as a binder in cements, as a sealant, and in the manufacture of detergents. Additionally, sodium silicate serves as a corrosion inhibitor and is utilized in the production of silica gel. The compound is also notable for its ability to form silicate gels when mixed with acids or certain salts. Its versatility extends to applications in agriculture, where it can enhance soil quality, and in the textile industry for fabric treatment. Safety precautions should be observed when handling sodium silicate, as it can cause skin and eye irritation due to its alkaline nature.
