Knowra Sodium metasilicate Sodium metasilicate Sodium metasilicate is an inorganic sodium silicate with the formula Na₂SiO₃. It is an alkaline solid used in detergents, cleaners, and industrial processes.
Sodium silicate : Sodium silicates are compounds of sodium, silicon, and oxygen, often supplied as alkaline aqueous solutions or solids. Sodium metasilicate is one defined composition within this broader family of soluble silicates.
Laundry detergent : Laundry detergent is a cleaning formulation designed to remove soils from textiles during washing. Metasilicate can serve as an alkaline builder in some detergent formulations.
Metasilicic acid : Metasilicic acid is a formal silicic-acid composition represented by H₂SiO₃, though it is not generally isolated as a stable pure substance. The name sodium metasilicate describes the sodium salt composition associated with this acid.
Sodium orthosilicate : Sodium orthosilicate is a sodium salt with the composition Na₄SiO₄, containing orthosilicate ions. Its silicate-to-sodium ratio differs from metasilicate, producing a distinct compound.
Hydrolysis : Hydrolysis is a chemical reaction in which a substance reacts with water, often changing the solution’s acidity or composition. Dissolved metasilicate forms alkaline solutions through reactions involving water.
Dishwashing detergent : Dishwashing detergent is a formulation that removes food residues and grease from dishes and utensils. Its alkalinity can support removal of greasy soils in industrial dishwashing products.
Silicon dioxide : Silicon dioxide is a compound of silicon and oxygen found in forms including quartz and amorphous silica. Its silicon–oxygen framework is the structural basis of silicate compounds.
Sodium disilicate : Sodium disilicate is a sodium silicate containing silicate units with a silicon-to-oxygen ratio different from metasilicate. It represents a more silica-rich silicate composition used in some detergent applications.
Alkalinity : Alkalinity is a solution’s capacity to neutralize acids, usually arising from dissolved bases and related ions. Its alkaline solutions help loosen greasy soils and neutralize acidic residues.
Alkaline cleaning : Alkaline cleaning uses basic solutions to remove soils such as fats, oils, and proteins. Metasilicate is used as a builder or active alkaline ingredient in these cleaners.
