The table below is calculated from the molecular formula H2NaO4P. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains the metallic element Na. The material behaves as an inorganic salt: it is non-volatile, generally water-soluble, and leaves an inorganic residue on ignition.
Contains phosphorus. Phosphate-type structures complex metal ions, which matters in hardness control and in the stability of a formulated system.
At 119.98 g/mol the molar mass is in the small-molecule range, where volatility and dust generation are the practical handling concerns.
