Description
Sodium nitrate (CAS 7631-99-4) is a crystalline inorganic salt offered at a minimum purity of 99 % and formulated with an anti-caking agent for reliable handling. Its empirical formula is NaNO₃, with a molar mass of 84,99 g/mol and a density of 2,26 g/cm³. Sodium nitrate is widely applied as an oxidising reagent, a nitrogen source in inorganic synthesis and a component in analytical or process formulations. The material from manufacturer Carl ROTH is identified by EG number 231-554-3 and UN number 1498, consistent with its classification as an oxidising solid. The free-flowing crystalline form aids accurate dosing, while the anti-caking additive helps preserve pourability during repeated container opening. Suitable for teaching laboratories, quality-control workflows and applied chemistry, this sodium nitrate provides a consistent starting material for inorganic and general laboratory applications without unnecessary complexity in day-to-day use.

Questions about Sodium nitrate, min. 99 % cryst., with anti-caking agent, 100 g, plastic
What is this article?
Sodium nitrate, min. 99 % cryst., with anti-caking agent, 100 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.
