Description
Potassium chloride solution, 3 mol/l is a volumetric standard solution equivalent to 3 N and saturated with AgCl. Based on the salt with CAS number 7447-40-7 and empirical formula KCl, the solute has a molar mass of 74,56 g/mol. The ready solution shows a density of approximately 1,13 g/cm³ and a boiling point of 100 °C. It is formulated for analytical chemistry applications that require a defined potassium chloride concentration, including electrochemical measurements and related volumetric work. The EG number is 231-211-8. Saturation with silver chloride makes the medium particularly relevant where chloride electrolytes compatible with Ag/AgCl reference systems are needed. Clear labelling as 3 mol/l – 3 N helps analysts prepare, verify, and document methods with confidence in teaching and professional analytical environments.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium chloride solution, 250 ml, 3 mol/l - 3 N, volumetric standard solution
What is this article?
Potassium chloride solution, 250 ml, 3 mol/l - 3 N, volumetric standard solution 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.
