Description
Sodium sulphate is an anhydrous inorganic salt offered at min. 99 % purity, with CAS number 7757-82-6 and empirical formula Na₂SO₄. It has a molar mass of 142,04 g/mol and a density of 2,7 g/cm³, providing well-defined physical data for laboratory planning and formulation work. Anhydrous sodium sulphate is commonly employed as a drying agent and sorbent in performance-materials and filtration contexts, where removal of residual moisture from organic phases or process streams is required. The product is EG number 231-820-9 completes the standard European substance identification. With its high minimum assay, anhydrous form and robust pack size, this sodium sulphate supports drying, sorbent and related laboratory applications that depend on a reliable, low-water inorganic salt.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about Sodium sulphate, min. 99 %, anhydrous, 2.5 kg, plastic
What is this article?
Sodium sulphate, min. 99 %, anhydrous, 2.5 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?
