The Properties and Specifications of Potassium Bicarbonate:
Potassium Bicarbonate USP Grade Specifications
KHCO3 100.12
Carbonic acid, monopotassium salt.
Monopotassium carbonate CAS 298-14-6
Potassium Bicarbonate contains not less than 99.5 percent and not more than 101.5 percent of KHCO3, calculated on the dried basis.
Identification: A solution (1 in 10) responds to the tests for Potassium and for Bicarbonate .
Loss on drying: Dry it over silica gel for 4 hours: it loses not more than 0.3% of its weight.
Normal carbonate: Grind 3.0 g of Potassium Bicarbonate with 25 mL of alcohol and 5 mL of water in a porcelain mortar. Add 3 drops of PhPh TS, and titrate slowly with barium chloride solution, prepared by dissolving 12.216 g of barium chloride in 300 mL of water and diluting with alcohol to obtain 1000 mL of solution, until the suspension becomes colorless. Continue the grinding for 2 minutes, and if the color turns pink, continue the titration with the barium chloride solution to a colorless end-point. Repeat the grinding for 2 minutes and the addition of the barium chloride solution, if necessary, until the suspension is colorless after 2 minutes of grinding. Each mL of the barium chloride solution is equivalent to 6.911 mg of K2CO3: not more than 2.5% is found.
Heavy metals: To 2 g add 5 mL of water and 8 mL of 3 N hydrochloric acid, heat to boiling, and maintain that temperature for 1 minute. Add 1 drop of PhPh and sufficient 6 N ammonium hydroxide, drop wise, to give the solution a faint pink color. Cool, add 2 mL of 1 N acetic acid, and then dilute with water to 25 mL: the limit is 0.001%.
