Sodium silicate formula

Water glass is the “magic” solution used to grow magic rocks. Anne and Todd Helmenstine Water glass is the common name for an aqueous solution of either sodium silicate or potassium silicate. It’s also called “liquid glass”. It gets its name because it’s essentially glass (silicon dioxide) in water. As the water evaporates, the solution solidifies into a glassy solid. Chemical Formula of Water Glass The most common formula isNa 2(SiO 2) nO, althoughK 2(SiO 2) nO is also a form of water glass. Water Glass Properties IUPAC ID:Sodium metasilicate or potassium metasilicate Formula:Na 2O 3Si Appearance: Colorless when pure, common pale green or blue from iron-bearing impurities. The solid is usually a white powder that dissolves in water to yield an alkaline solution. Density:2.40-2.61 g/cm³ Molar mass:122.06g/mol Melting point:1,990°F (1,088°C) Solubility: Soluble in water, insoluble in alcohol. Discovery: Around 1940Jean Baptist van Helmontobserved water glass as a fluid produced by melting together sand and excess alkali. The chemical was defined in the 1892 translation ofVon Wagner’s Manual of Chemical Technology. Manufacture: Quartz sand and alkali are reacted in either the liquid or solid phase to produce water glass. Sodium carbonate or caustic soda are common alkaline materials used in the process. Water Glass Uses Water glass is used to make silica gel beads or packets, which are used to protect clothing and electronics from moisture. The chemical is used in passive fi...

Sodium Silicate Materials All you need to make a sodium silicate solution are water, silica, and sodium hydroxide. Silica comes in those little packets labeled "Do not eat" that you find with electronics, shoes, and other products. Sodium hydroxide is readily available in its pure form or can be found Prepare Sodium Silicate • Wear proper safety gear, which includes gloves. • Heat 4 to 8 grams of sodium hydroxide in 10 milliliters of water. • Once the sodium hydroxide is dissolved, slowly add 6 grams of crushed silica gel beads. Heat the solution between additions. If the crushed beads won't dissolve, add a little more water to the solution. • You now have sodium silicate or water glass.

This material is often called “water glass” and is ordinarily supplied as a colorless, viscous water solution displaying little tack. Positive pressure must be used to hold the substrates together. This material will withstand temperatures of up to 1100°C. The main applications of sodium silicate adhesives are in bonding paper and making corrugated boxboard, boxes, and cartons. They are also used in wood bonding and in bonding metal sheets to various substrates; in bonding glass to glass, porcelain, leather, textiles, stoneware, and so on; bonding glass-fiber assemblies; optical glass applications; manufacture of shatter-proof glass; bonding insulation materials; refractory cements for tanks, boilers, ovens, furnaces; acid-proof cements; fabrication of foundry molds; briquettes; and abrasive polishing wheel cements. Soluble silicates may also be reacted with silicon fluorides or silica to produce acid-resistant cements with low shrinkage and a thermal expansion...

water glass, also called sodium silicate or soluble glass, a 2O) and 2) that forms a glassy solid with the very useful property of being soluble in water. Water Water glass has been manufactured since the 19th century, and the basic principles of making “silicate of soda” have not changed since that time. It is commonly produced by roasting various quantities of soda ash (sodium carbonate, Na 2CO 3) and silica sand (a 2) in a furnace at temperatures between about 1,000 and 1,400 °C (approximately 1,800 and 2,500 °F), a process that gives off 2) and produces sodium silicate (Na 2SiO 3; usually represented by its two 2 2): Na 2CO 3 + SiO 2→ Na 2O∙SiO 2 + CO 2 industrial glass: Sodium silicate glass This roasting produces fused glassy lumps called cullet, which can be cooled and sold in that form or ground up and sold as powders. Lump or ground water glass in turn can be fed into pressurized reactors for dissolving in hot water. The Sodium silicate liquid can also be prepared directly by dissolving silica sand under pressure in a heated aqueous solution of 2NaOH + SiO 2 → Na 2O∙SiO 2 + H 2O In either production route, the higher the ratio of SiO 2 to Na 2O and the higher the concentration of both ingredients, the more These properties make hydrated sodium silicates ideal for use in one of their most common consumer products: powdered laundry and dishwasher Get a Britannica Premium subscription and gain access to exclusive content.

Sodium silicate is a generic name for Na 2 xSi yO 2 y+ x or (Na 2O) x· (SiO 2) y, such as Na 2SiO 3, Na 4SiO 4, and Na 6Si 2O 7. The anions are often Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of In industry, the various grades of sodium silicate are characterized by their SiO 2:Na 2O weight ratio (which can be converted to molar ratio by multiplication with 1.032). The ratio can vary between 1:2 and 3.75:1. 2:Na 2O ratio are described as neutral. History [ ] Soluble silicates of tartari salis (cream of tartar, crystallum (quartz) to melt at a lower temperature.
