Potassium Nitrate
CAS Number: 7757-79-1
Molecular Formula: KNO3
Molecular Weight: 101.1
Potassium Nitrate
Potassium Nitrate USP Grade Specifications
Potassium Nitrate
KNO3 -- 101.10
Potassium nitrate.
Potassium nitrate CAS 7757-79-1
Potassium Nitrate contains not less than 99.0 percent and not more than 100.5 percent of KNO3.
Identification: A solution of it responds to the tests for Potassium and for Nitrate.
Chloride: A 500-mg portion of it shows no more chloride than corresponds to 0.21 mL of 0.020 N hydrochloric acid (0.03%).
Sulfate: Dissolve 100 mg of Potassium Nitrate in 10 mL of water, add 15 mL of 6 N hydrochloric acid, and evaporate to dryness on a steam bath. To the residue so obtained add 7 mL of 6 N hydrochloric acid, and evaporate to dryness on a steam bath. Dissolve the residue so obtained in about 35 mL of water and, if necessary, neutralize with hydrochloric acid using litmus paper indicator. Filter, if necessary, to obtain a clear test solution. This test solution shows no more sulfate than corresponds to 0.10 mL of 0.020 N sulfuric acid (0.1%).
Arsenic: 3 ppm.
Lead: A solution of 0.5 g of it in 20 mL of water contains not more than 5 4g of lead (corresponding to not more than 0.001% of Pb).
Heavy metals: 0.002%.
Iron: not more than 0.001%.
Limit of sodium: the limit is 0.1%.
Limit of nitrite: To pass the test.
Potassium Nitrate FCC Food Grade Specifications
KNO3 Formula weight 101.10
INS: 252 CAS 7757-79-1
DESCRIPTION
Potassium Nitrate occurs as colorless, transparent prisms, as white granules, or as a white, crystalline powder. It is slightly hygroscopic in moist air. One gram dissolves in 3 mL of water at 25C, in 0.5 mL of boiling water, and in about 620 mL of alcohol. Its solutions are neutral to litmus.
Function: Antimicrobial agent; preservative.
REQUIREMENTS
Identification: A 1:10 aqueous solution gives positive tests for Potassium and Nitrate.
Assay: Not less than 99.0% and not more than 100.5% of KNO3 after drying.
Chlorate: Sprinkle about 100 mg of dry sample on 1 mL of sulfuric acid. The mixture does not turn yellow.
Lead: Not more than 4 mg/kg.
Loss on Drying: Not more than 1%.
