Description
Sodium tetraphenyl borate solution is a 0,05 mol/l (0,05 M) volumetric solution of sodium tetraphenyl borate, CAS number 143-66-8, with empirical formula C₂₄H₂₀BNa and molar mass 342,23 g/mol. The reagent is supplied as a 1 liter pack with a package weight of 1,300 kg. Density is approximately 1 g/cm³ and the boiling point is 100 °C. EG number 205-605-5 identifies the dissolved sodium tetraphenyl borate. Prepared as a 0,05 M volumetric solution, the product belongs to the class of volumetric standard solutions used in analytical chemistry. The solution from manufacturer Carl ROTH provides a defined 0,05 mol/l titre of C₂₄H₂₀BNa in a 1 liter unit quantity. Physical data of density ~1 g/cm³ and boiling point 100 °C describe the liquid character of this volumetric reagent. CAS 143-66-8, EG number 205-605-5, molar mass 342,23 g/mol and formula C₂₄H₂₀BNa specify the solute, while the 0,05 mol/l - 0,05 M designation specifies the working concentration of the 1 liter volumetric solution for laboratory analytical use.

Questions about Sodium tetraphenyl borate solution, 0,05 mol/l volumetric solution, 1 l
What is this article?
Sodium tetraphenyl borate solution, 0,05 mol/l 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.
