Sodium silicate 20litres
0 out of 5(0)Sodium silicate, commonly known as water glass or liquid glass, is a compound containing sodium oxide (Na₂O) and silica (SiO₂). It is typically represented by the formula Na2SiO3\text{Na}_2\text{SiO}_3Na2SiO3, but it can vary, forming a range of compositions depending on the ratio of sodium oxide to silica.
Properties
- Physical State: It is usually found in a glassy, crystalline solid form or as a thick, syrupy liquid.
- Appearance: Colorless to light brown.
- Solubility: Highly soluble in water, forming a viscous solution.
- pH: Alkaline, typically around 11-12.
Production
Sodium silicate is produced by fusing sodium carbonate (soda ash) and silica sand at high temperatures. The general reaction is: Na2CO3+SiO2→Na2SiO3+CO2\text{Na}_2\text{CO}_3 + \text{SiO}_2 \rightarrow \text{Na}_2\text{SiO}_3 + \text{CO}_2Na2CO3+SiO2→Na2SiO3+CO2
