Description
Sodium sulphate is an anhydrous inorganic salt offered at min. 98,5 % purity in Ph.Eur. quality. With CAS number 7757-82-6, empirical formula Na₂SO₄ and EG nr. 231-820-9, it has a molar mass of 142,04 g/mol and a density of 2,7 g/cm³. The anhydrous solid is Manufacturer Carl ROTH supplies this pharmacopoeia-grade salt for applications such as drying of organic phases, preparation of standard solutions, and use as an inorganic reagent where defined sulphate content is important. Its anhydrous form and Ph.Eur. specification make it a reliable choice for laboratories requiring consistent sodium sulphate for sample preparation, formulation support and routine inorganic chemistry.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about Sodium sulphate, min. 98,5 %, Ph.Eur., anhydrous, 500 g, plastic
What is this article?
Sodium sulphate, min. 98,5 %, Ph.Eur., anhydrous, 500 g, 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.
