Description
Potassium persulphate min. 99 %, extra pure is an inorganic oxidising salt with CAS number 7727-21-1 and empirical formula K₂S₂O₈. It exhibits a molar mass of 270,32 g/mol and a density of 2,48 g/cm³, making it suitable for oxidation chemistry, polymerisation initiation and analytical sample preparation. This potassium persulphate from manufacturer Carl ROTH is used where strong peroxydisulphate oxidation is required under controlled conditions. Typical contexts include chemical synthesis, environmental sample treatment and general laboratory reagent stock. The crystalline solid dissolves readily in aqueous systems for preparation of working oxidant solutions. With defined purity of at least 99 %, it provides a dependable source of persulphate for research and routine analytical work across chemical A-to-Z inventories.

Questions about Potassium persulphate, min. 99 %, extra pure, 1 kg, plastic
What is this article?
Potassium persulphate, min. 99 %, extra 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.
