The standard limits the mass fractions of water-insoluble substances, residue after ignition, heavy metals, and manganese.
Typically requires high purity, often around 98-99.9%. nadsernokislyj ammonij gost
The quality of the reagent is categorized into different grades (e.g., "pure for analysis" or "ch.d.a.") with specific physicochemical requirements: The standard limits the mass fractions of water-insoluble
Typically ranges between 3.0 and 5.0 for a 5% or 50g/L solution. The standard is currently active and has been
