KH2PO4 -- 136.1 -- CAS 7778-77-0
Monobasic Potassium Phosphate
Potassium Phosphate Monobasic

DEFINITION
Potassium dihydrogen phosphate contains not less than 98.0 per cent and not more than the equivalent of 100.5 per cent of KH2PO4, calculated with reference to the dried substance.

CHARACTERS
A white, crystalline powder or colourless crystals, freely soluble in water, practically insoluble in alcohol.

IDENTIFICATION
A. Solution S (see Tests) is faintly acid.
B. Solution S gives reaction (b) of phosphates.
C. 0.5 ml of solution S gives reaction 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.
pH: To 5 ml of solution S add 5 ml of carbon dioxide-free water. The pH of the solution is 4.2 to 4.5.
Reducing substances: To 5 ml of solution S add 5 ml of dilute sulphuric acid and 0.25 ml of 0.02 M potassium permanganate. Heat on a water-bath for 5 min. The colour of the permanganate is not completely discharged.
Chlorides: Dilute 2.5 ml of solution S to 15 ml with water R. The solution complies with the limit test for chlorides (200 ppm).
Sulphates: To 5 ml of solution S add 0.5 ml of hydrochloric acid and dilute to 15 ml with distilled water. The solution complies with the limit test for sulphates (300 ppm).
Arsenic: 0.5 g complies with limit test A for arsenic (2 ppm).
Iron: 10 ml of solution S complies with the limit test for iron (10 ppm).
Sodium: If intended for use in the manufacture of parenteral dosage forms, it complies with the test for 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 2.0 per cent, determined on 1.000 g by drying in an oven at 125C to 130C.
