    P:260c-280c-301+330+331-305+351+338-309+310
    HNO3 MW 63.01 d 1.42 CAS [7697-37-2]
    Assay 67-69%
    Trace elemental impurities: parts per trillion level
    Batch values reported on accompanying Certificate of Analysis
    Store in dark.
    Application: Ultra trace inorganic analysis
    Concentrated Nitric Acid can decompose to nitrogen oxides (NOx) through action of heat or light resulting in a yellow colouration. However, this does not affect the performance of the acid with respect to trace metals or oxidising power.
    Storage in a cool, dark place is recommended.
