Description
Potassium chloride solution 0,5 mol/l – 0,5 N is a ready-to-use volumetric standard solution with empirical formula KCl, CAS number 7447-40-7 and molar mass 74,56 g/mol. Featuring a density of 1,022 g/cm³ and a boiling point of 100 °C, this analytical reagent is suited to precise titration, calibration and standardisation tasks in the laboratory. The product is supplied in a 1 l pack for convenient handling in routine volumetric analysis where 0,5 N normality is specified. Applications include electrochemical measurements, reference electrode procedures and general analytical chemistry workflows in quality-control and research environments. Available from manufacturer Carl ROTH, the solution offers defined concentration together with clearly stated physical data for method documentation. EG number 231-211-8 supports straightforward identification in laboratory systems. This potassium chloride volumetric standard enables reliable day-to-day performance without further dilution when 0,5 mol/l strength is required.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Potassium chloride solution, 0.5 mol/l -0.5 N volumetric standard solution, 1 l
What is this article?
Potassium chloride solution, 0.5 mol/l -0.5 N volumetric standard solution, 1 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is ICP, AAS & ion standards. The catalogue is Lab chemicals.
Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
