Description
Potassium chloride solution 3,5 mol/l – 3,5 N is a volumetric solution with empirical formula KCl and CAS number 7447-40-7, supplied saturated with AgCl. The defined 3,5 mol/l (3,5 N) concentration, combined with silver chloride saturation, supports specialised volumetric and electrochemical laboratory applications that require this specific matrix. Reported properties include a molar mass of 74,56 g/mol, a density of approximately 1,15 g/cm³ and a boiling point of 100 °C, facilitating controlled handling under standard conditions. The product is provided in a 1 l pack size for practical use in analytical and quality-control environments. Available from manufacturer Carl ROTH within its range of volumetric solutions for analytical chemistry, it carries EG number 231-211-8. Laboratories benefit from a ready-prepared format that delivers consistent concentration and AgCl saturation without additional preparation steps. This potassium chloride volumetric solution is suited to methods where a higher-strength KCl medium saturated with silver chloride is specified, supporting reproducible results in routine and specialised analytical workflows.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium chloride solution, 3.5 mol/l - 3.5 N volumetric solution, , 1 l
What is this article?
Potassium chloride solution, 3.5 mol/l - 3.5 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.
