Description
Sodium hydroxide solution ROTI®Volum 0,5 mol/l - 0,5 N is a higher-strength volumetric concentrate supplied in ampoule form for preparation of a 0,5 N alkaline working solution. CAS number 1310-73-2, empirical formula NaOH and molar mass 40,01 g/mol define the chemical identity. Density ranges from 1,2 to 1,3 g/cm³, with a boiling point of 100 °C. EG number 215-185-5 and UN number 1824 are listed for the substance. Packaged as 1 pc ampoule from manufacturer Carl ROTH within the ROTI®Volum series, it is intended for acid–base titrations and related volumetric procedures that benefit from a half-normal sodium hydroxide standard. The sealed ampoule supports accurate dilution immediately before use and suits analytical, quality-control and instructional laboratories performing titration work. This 0,5 mol/l grade complements lower-strength hydroxide volumetrics when a stronger titre is preferred, while retaining the convenience of single-unit ampoule handling for reproducible alkaline standards in routine laboratory practice.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sodium hydroxide solution, ROTI®Volum 0,5 mol/l - 0,5 N, ampoule, 1 pc
What is this article?
Sodium hydroxide solution, ROTI®Volum 0,5 mol/l - 0,5 N, ampoule, 1 pc 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.
