Description
Potassium nitrate (KNO₃, CAS number 7757-79-1) is an inorganic salt of minimum 99 % purity, offered as a free-flowing p.a., ACS reagent for analytical chemistry. Its empirical formula is KNO₃, with a molar mass of 101,11 g/mol and a density of 2,1 g/cm³. The salt is supplied in a 500 g pack for laboratory use in qualitative detection reagents and cation detection. Potassium nitrate from manufacturer Carl ROTH is identified by EG nr. 231-818-8 and UN number 1486. The combination of p.a. and ACS grade with a minimum assay of 99 % specifies the chemical quality of this potassium nitrate for analytical work. The free-flowing character assists handling and weighing when the solid is taken into solution or mixed with other reagents. In qualitative inorganic analysis, KNO₃ provides potassium cations and nitrate anions in a single, compositionally defined compound. CAS number, molar mass and density can be transferred directly into laboratory method documentation for this 500 g analytical reagent.
