Description
tri-Sodium phosphate dodecahydrate is an analytical-grade inorganic salt with a minimum assay of 98 %, offered as p.a., ACS material for laboratory use. Identified by CAS number 10101-89-0 and empirical formula Na₃PO₄ · 12 H₂O, it has a molar mass of 380,12 g/mol and a density of 1,62 g/cm³. The dodecahydrate form provides a defined hydrate content that supports reproducible preparation of phosphate solutions and related inorganic procedures. Its placement among salts for analysis (p.a.) reflects the need for controlled purity in classical wet chemistry and instrumental sample preparation. Density and molar-mass values assist stoichiometric calculations and method documentation. Available from manufacturer Carl ROTH, this reagent combines ACS-aligned specification with practical packaging for everyday laboratory logistics. EG number 231-509-8 supports regulatory and inventory identification alongside the CAS reference, giving laboratories a clear, fully specified phosphate salt for routine analytical tasks.

Questions about tri-Sodium phosphate dodecahydrate, min. 98 %, p.a., ACS, 1 kg, plastic
What is this article?
tri-Sodium phosphate dodecahydrate, min. 98 %, p.a., ACS, 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.
