Description
Sodium hydroxide solution 0,025 mol/l - 0,025 N is a volumetric standard solution for analytical titration and related laboratory work. The reagent corresponds to CAS number 1310-73-2 and EG number 215-185-5, with empirical formula NaOH and a molar mass of 40,01 g/mol. Density is approximately 1 g/cm³ and the boiling point is about 100 °C, reflecting the dilute aqueous character of this titre. Supplied in a 1 l pack, the solution is suited to routine volumetric analysis where a defined 0,025 mol/l (0,025 N) sodium hydroxide concentration is required. Analytical chemistry laboratories use such volumetric standard solutions for acid–base titrations, standardisation steps, and general wet-chemical procedures that demand a known normality. This preparation is available from manufacturer Carl ROTH for controlled dispensing in titration benches and automated or manual analytical setups. Clear CAS, EG, and concentration labelling supports method documentation, inventory management, and safe handling under laboratory chemical hygiene practice. Apply according to validated analytical methods and institutional safety requirements for alkaline solutions (UN 1824).

Questions about Sodium hydroxide solution, 0,025 mol/l - 0,025 N volumetric solution, 1 l
What is this article?
Sodium hydroxide solution, 0,025 mol/l - 0,025 N volumetric solution, 1 l 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.
