Beschreibung
Potassium hydrogen phthalate solution ROTI®Star 0,1 mol/l - 0,1 N is a volumetric solution of potassium hydrogen phthalate (CAS 877-24-7, empirical formula C₈H₅KO₄) at a concentration of 0,1 mol/l corresponding to 0,1 N. The molar mass is 204,23 g/mol. It is offered in a 500 ml pack and shows a density of approximately 1 g/cm³ together with a boiling point of about 100 °C. This ROTI®Star volumetric solution from manufacturer Carl ROTH is intended for analytical chemistry as a volumetric standard solution. Laboratories use potassium hydrogen phthalate at 0,1 mol/l - 0,1 N in volumetric titration and quantitative procedures that specify this titre. The 500 ml quantity provides a practical volume for routine titre work in the chemical laboratory. Reported physical data, including density around 1 g/cm³ and boiling point near 100 °C, inform handling of the volumetric reagent. ROTI®Star 0,1 mol/l - 0,1 N identifies the concentration grade of this potassium hydrogen phthalate volumetric solution for standardisation. The preparation belongs to the ROTI®Star volumetric standard solutions used in analytical workflows.
