Na2011SiO2

The chemical formula Na2O 11SiO2 represents a sodium silicate compound. This compound falls within the broader family of soluble silicates, often referred to as water glass. The ratio of sodium oxide (Na2O) to silicon dioxide (SiO2) is approximately 1:11, indicating a high silica content relative to sodium.

Sodium silicates are typically produced by fusing sand (silicon dioxide) with sodium carbonate (soda ash) at high temperatures. The exact properties and applications of sodium silicates are highly dependent on their molar ratio of Na2O to SiO2. Compounds with higher silica content, like Na2O 11SiO2, tend to have different solubility characteristics and reactivity compared to those with lower silica content.

In its solid form, sodium silicate is often amorphous and glassy. When dissolved in water, it forms alkaline solutions. These solutions are utilized in a variety of industrial applications. Due to their adhesive properties, they are used in detergents as binders, in paper manufacturing to strengthen cardboard, and as a flux in welding rods. Their ability to bind and seal also finds use in construction for concrete hardening and waterproofing. The specific applications of a compound with the 1:11 ratio would be tailored to its particular characteristics within the sodium silicate spectrum.
