Description
ortho-Phosphoric acid 0,1 mol/l – 0,3 N volumetric solution is a ready-to-use analytical reagent supplied as H₃PO₄ for precise titration and standardisation work. With CAS number 7664-38-2, molar mass 98,00 g/mol and empirical formula H₃PO₄, this solution supports reproducible acid–base determinations in quality-control and research laboratories. Density is 1,004 g/cm³ and the boiling point is 100 °C, consistent with a dilute aqueous phosphoric acid preparation. The product is filled in a 1 l plastic bottle for convenient bench handling and storage of volumetric standards. Manufactured by Carl ROTH, it belongs to the volumetric standard solutions range used for analytical chemistry workflows where defined normality (0,3 N) and molarity are required. Typical applications include titration of bases, preparation of secondary standards and routine assay procedures that demand a stable phosphoric acid titrant of known concentration.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about ortho-Phosphoric acid, 0,1 mol/l - 0,3 N volumetric solution, 1 l, plastic
What is this article?
ortho-Phosphoric acid, 0,1 mol/l - 0,3 N volumetric solution, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Volumetric standard solutions (titration), inside Analytical standards & reference materials, in Lab chemicals.
A volumetric standard solution is a reagent of stated concentration for titration, such as a stated molarity of acid, base or silver nitrate. The factor or the exact titre is on the certificate. Using the nominal molarity when a factor is printed is a systematic error.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
