Description
Potassium chromate solution ROTI®Star 1/30 mol/l - 0,0333 M is a volumetric solution of potassium chromate (CAS number 7789-00-6) with empirical formula K₂CrO₄ and a molar mass of 194,21 g/mol. Supplied in a 500 ml plastic bottle, the reagent is prepared at 1/30 mol/l (0,0333 M) for use as a ready-to-use titre in analytical chemistry. The aqueous preparation has a density of approximately 1 g/cm³ and a boiling point of 100 °C. Volumetric potassium chromate solutions are employed in wet-chemical analysis whenever a defined chromate concentration is required, supporting titration protocols and related laboratory methods that specify this molarity. The ROTI®Star presentation from manufacturer Carl ROTH is offered among volumetric standard solutions for routine analytical work. With EG number 232-140-5, the dissolved salt is clearly identified for laboratory inventory and documentation. The 500 ml plastic pack size is practical for bench-scale consumption, while the stated 1/30 mol/l concentration allows analysts to follow methods that call for this titre without preparing the solution from solid potassium chromate.

Questions about Potassium chromate solution ROTI®Star 1/30 mol/l - 0,0333 M, 500 ml
What is this article?
Potassium chromate solution ROTI®Star 1/30 mol/l - 0,0333 M, 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.
