What can dissolve sodium silicate?
Water
Sodium metasilicate/Soluble in
I recently discovered (through Wikipedia) that water glass / sodium Silicate dissolves in water (22 g / 100 ml @ 25 degrees and 160 g / 100 ml @ 80 degrees).
What is sodium silicate and its uses?
Sodium silicates are used in industry as adhesives, detergents, ingredients in cleaning compounds, cements, binders, and unique coatings, as well as coagulant aids, anticorrosives, catalyst bases, deflocculants, chemicals, zeolites, etc.
How do you precipitate sodium silicate?
Production. The production of precipitated silica starts with the reaction of an neutral silicate solution with a mineral acid. Sulfuric acid and sodium silicate solutions are added simultaneously with agitation to water. Precipitation is carried out under acidic conditions.
What is sodium silicate side effects?
Ingesting sodium silicate is unlikely; however, if ingested, it is moderately toxic and may cause pain and burns of the esophagus and gastrointestinal tract with vomiting, nausea, and diarrhea. There are no known chronic hazards associated with sodium silicates.
Is sodium silicate waterproof?
It forms a hard, glasslike mass when it dries. Sodium silicate has been used to preserve eggs, fireproof fabrics, and waterproof walls.
Which is another name for sodium silicate?
waterglass
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.
What is sodium silicate known as?
water glass, also called sodium silicate or soluble glass, a compound containing sodium oxide (Na2O) and silica (silicon dioxide, SiO2) that forms a glassy solid with the very useful property of being soluble in water.
What is the difference between precipitated and fumed silica?
While fumed silica is often used as a matting agent by conservators, its efficacy has been called into question. Fumed silica is produced commercially as a thickening or thixotropic agent, not as a matting agent; in contrast, precipitated silica is sold specifically as a matting agent.
How do you make silica gel from sodium silicate?
Silica gels were prepared by a simple experimental procedure at ambient temperature using sodium silicate. First, 5ml sodium silicate was added to 50ml deionized water, and then diluted sulfuric acid was added dropwisely to reach pH values of 6, 7 and 8.
