Sodium Metasilicate (Na₂SiO₃) is a white, crystalline powder used primarily as a cleaning agent and in industrial applications. It acts as a powerful alkaline detergent, commonly found in household and industrial cleaners due to its ability to dissolve grease and grime. Additionally, Sodium Metasilicate is used in water treatment processes to soften water and in construction as a concrete additive to enhance durability. Its effectiveness in cleaning and versatility in applications make it an essential compound in maintaining cleanliness and improving material properties.
