Ammonium Chloride USP
Assay- Ammonium Chloride contains not less than 99.5 percent and not more than 100.5 percent of NH4Cl, calculated on the dried basis.
Packaging and storage- Preserve in tight containers.
Identification- A solution (1 in 10) responds to the tests for Ammonium and for Chloride
pH between 4.6 and 6.0, in a solution (1 in 20).
Loss on drying- Dry it over silica gel for 4 hours: it loses not more than 0.5% of its weight.
Residue on ignition- Add 1 mL of sulfuric acid to about 2 g, accurately weighed, and heat the mixture gently until volatilization is complete: the residue is white, and when ignited, not more than 0.1% of nonvolatile substance remains.
Limit of thiocyanate- Acidify 10 mL of a solution (1 in 10) with hydrochloric acid, and add a few drops of ferric chloride TS: no orange-red color is produced.
Heavy metals : 0.001%.
