Potassium chromate solution ROTI®Star 1/30 mol/l - 0,0333 M, 500 ml

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.
