Description
Potassium nitrate is an inorganic laboratory salt offered at a minimum purity of 99 % and formulated with an anti-caking agent for freer flow during storage and dispensing. It is identified by CAS number 7757-79-1, empirical formula KNO₃, molar mass 101,11 g/mol and density 2,1 g/cm³, together with EG number 231-818-8 and UN number 1486. This provides a practical quantity for analytical preparations, reagent formulation and general inorganic chemistry workflows. The anti-caking additive helps limit clumping so the solid remains easier to weigh and transfer under routine laboratory conditions. Supplied by manufacturer Carl ROTH, the material suits teaching laboratories, research groups and quality-control settings that need a clearly specified potassium nitrate stock. Documented identifiers support traceability in experimental protocols and inventory systems. The plastic packaging is convenient for bench use and intermediate storage, while the defined purity and physical data allow straightforward integration into standard laboratory procedures without additional interpretation of the grade.

Questions about Potassium nitrate, min. 99 %, with anti-caking agent, 500 g, plastic
What is this article?
Potassium nitrate, min. 99 %, with anti-caking agent, 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.
