Description
Sodium metasilicate pentahydrate is an inorganic silicate salt in pure quality for general laboratory and technical chemical use. It is registered under CAS number 10213-79-3 and EG nr. 600-297-4, with empirical formula Na₂SiO₃ · 5 H₂O and a molar mass of 212,16 g/mol. The solid shows a density of 2,61 g/cm³ and is further associated with UN number 3253 for transport classification. As a hydrated metasilicate, it is employed where alkaline silicate chemistry is required, including formulation work, cleaning-related preparations and inorganic synthesis or process chemistry. This variant is Physical constants and identity data from manufacturer Carl ROTH allow straightforward specification against internal methods and safety documentation. The pure grade supports applications that need a defined sodium metasilicate pentahydrate source without additional branded specialty claims, fitting A-to-Z chemical inventories in research and industrial labs.

Questions about Sodium metasilicate pentahydrate, pure, 1 kg, plastic
What is this article?
Sodium metasilicate pentahydrate, pure, 1 kg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Inorganic salts. The catalogue is Lab chemicals.
