Specifications of Potassium Nitrate USP Grade Show/Hide Details
Potassium Nitrate USP Grade
KNO3 --- 101.10
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 BP Ph Eur Grade
KNO3 -- 101.1 -- CAS 7757-79-1
DEFINITION
Potassium nitrate contains not less than 99.0 per cent and not more than the equivalent of 101.0 per cent of KNO3, calculated with reference to the dried substance.
CHARACTERS
A white, crystalline powder or colourless crystals, freely soluble in water, very soluble in boiling water, practically insoluble in alcohol.
IDENTIFICATION
A. It gives the reaction of nitrates.
B. Solution S (see Tests) gives the reactions of potassium.
TESTS
Solution S: Dissolve 10.0 g in carbon dioxide-free water prepared from distilled water and dilute to 100 ml with the same solvent.
Appearance of solution: Solution S is clear and colourless.
Acidity or alkalinity: To 10 ml of solution S add 0.05 ml of bromothymol blue solution. Not more than 0.5 ml of 0.01 M hydrochloric acid or 0.01 M sodium hydroxide is required to change the colour of the indicator.
Reducible substances: To 10 ml of solution S, add 0.5 ml of dilute sulphuric acid and 2 ml of zinc iodide and starch solution. The solution does not become blue within 2 min.
Chlorides: If intended for ophthalmic use, it complies with the test for chlorides. Dissolve 2.5 g in water and dilute to 15 ml with the same solvent. The solution complies with the limit test for chlorides (20 ppm).
Sulphates: Dilute 10 ml of solution S to 15 ml with distilled water. The solution complies with the limit test for sulphates (150 ppm).
Ammonium: 1 ml of solution S complies with the limit test (A) for ammonium (100 ppm). If intended for ophthalmic use, not more than 50 ppm of ammonium.
Calcium: Dilute 10 ml of solution S to 15 ml with distilled water. The solution complies with the limit test for calcium (100 ppm). If intended for ophthalmic use, not more than 50 ppm of calcium.
Iron: Dilute 5 ml of solution S to 10 ml with water. The solution complies with the limit test for iron (20 ppm). If intended for ophthalmic use, not more than 10 ppm of iron.
Sodium: Not more than 0.1 per cent of Na, determined by atomic emission spectrometry.
Heavy metals: 12 ml of solution S complies with limit test A for heavy metals (10 ppm).
Loss on drying: Not more than 0.5 per cent determined on 1.000 g by drying in an oven at 100C to 105C.
