IDENTIFICATION A. Identification Tests-General, Potassium: Meets the requirements B. Identification Tests-General, Carbonate: Meets the requirements. ASSAY Procedure Sample: Dried potassium carbonate obtained in the test for Loss on Drying Analysis: Transfer the Sample to a flask with the aid of 150 mL of water and add 4 drops of methyl orange. Titrate with 1 N hydrochloric acid. Each mL of 1 N hydrochloric acid is equivalent to 69.11 mg of K2CO3. Acceptance criteria: 99.5% to 100.5% on the dried basis Loss on Drying: Dry a sample at 180C for 4 h: it loses NMT 0.5% of its weight. Insoluble Substances: Sample solution: 1 g in 20 mL of water Acceptance criteria: The solution is complete, clear, and colorless. Specifications of Potassium Carbonate BP Ph Eur Grade K2CO3 DEFINITION Content: 99.0 per cent to 101.0 per cent (dried substance). CHARACTERS Appearance: White or almost white granular powder, hygroscopic. Solubility: Freely soluble in water, practically insoluble in ethanol (96 per cent). IDENTIFICATION A. Dissolve 1 g in 10 ml of water. The solution is strongly alkaline. B. 2 ml of the solution prepared for identification test A gives the reaction of carbonates and bicarbonates. C. 1 ml of the solution prepared for identification test A gives reaction of potassium. TESTS Solution S: Dissolve 10.0 g in 25 ml of distilled water. Slowly add 14 ml of hydrochloric acid. When the effervescence has ceased, boil for a few minutes. Allow to cool and dilute to 50 ml with distilled water. Appearance of solution: Solution S is not more opalescent than reference suspension and not more intensely coloured than reference solution. Chlorides: Maximum 100 ppm. Sulphates: Maximum 100 ppm. Calcium: Maximum 100 ppm. Iron: Maximum 10 ppm. Heavy metals: Maximum 20 ppm. Loss on drying: Maximum 5.0 per cent, determined on 0.300 g by drying in an oven at 120-125C for 5 h. Specifications of Potassium Carbonate FCC Food Grade K2CO3 Formula wt, anhydrous 138.21 K2CO3-1½H2O Formula weight, hydrated 165.23 INS: 501(i) CAS 584-08-7 DESCRIPTION Potassium Carbonate is anhydrous or contains 1.5 molecules of water of crystallization. The anhydrous form occurs as a white, granular powder, and the hydrated form as small, white, translucent crystals or granules. It is very deliquescent, and its solutions are alkaline. One gram dissolves in 1 mL of water at 25C and in about 0.7 mL of boiling water. It is insoluble in alcohol. Function: pH control. REQUIREMENTS Identification: A 1:10 aqueous solution gives positive tests for Potassium and for Carbonate. Assay: Not less than 99.0% and not more than 100.5% of K2CO3 after drying. Insoluble Substances: Passes test. Lead: Not more than 2 mg/kg. Loss on Drying Anhydrous: Not more than 1%; Hydrated: Between 10.0% and 16.5%.
