Description
Potassium hydroxide solution ROTI®Star 1 mol/l - 1 N is a volumetric potassium hydroxide solution (empirical formula KOH, CAS number 1310-58-3) at 1 mol/l, equivalent to 1 N. Molar mass is 56,11 g/mol. The aqueous alkali has a density of approximately 1,05 g/cm³ and a boiling point of 100 °C. Packed as 500 ml in plastic, it is intended for volumetric standard work on the analytical bench. Potassium hydroxide solutions of defined concentration are used in acid–base titrations and related quantitative procedures that call for 1 mol/l or 1 N KOH. This ROTI®Star volumetric solution from manufacturer Carl ROTH provides that concentration in a laboratory pack, so the alkali is already dissolved at 1 mol/l. Analytical laboratories using volumetric standard solutions can employ the 500 ml plastic bottle wherever a 1 N potassium hydroxide solution is specified. Identification of the reagent rests on the formula KOH, the CAS number 1310-58-3 and the stated molar mass, density and boiling point of this aqueous preparation.

Questions about Potassium hydroxide solution ROTI®Star 1 mol/l - 1 N, 500 ml
What is this article?
Potassium hydroxide solution ROTI®Star 1 mol/l - 1 N, 500 ml 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?
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.
