Procedure
Sample: 4 g
Analysis: Dissolve the Sample in 100 mL of water, add methyl red TS, and titrate with 1 N hydrochloric acid. Add the acid slowly, with constant stirring, until the solution becomes faintly pink. Heat the solution to boiling, cool, and continue the titration until the pink color no longer fades after boiling. Each mL of 1 N hydrochloric acid is equivalent to 100.1 mg of KHCO3.
Acceptance criteria: 99.5% to 101.5% on the dried basis.
Normal Carbonate:
Sample: Grind 3.0 g of Potassium Bicarbonate with 25 mL of alcohol and 5 mL of water in a porcelain mortar.
Barium chloride solution: 12.216 mg/mL of barium chloride in alcohol and water (7:3), prepared by dissolving the barium chloride in water, then diluting with alcohol to final volume
Analysis: Add 3 drops of phenolphthalein to the Sample and titrate slowly with Barium chloride solution until the suspension becomes colorless. Continue the grinding for 2 min, and if the color turns pink, continue the titration with Barium chloride solution to a colorless endpoint. Repeat the grinding for 2 min and the addition of Barium chloride solution, if necessary, until the suspension is colorless after 2 min of grinding. Each mL of the barium chloride solution is equivalent to 6.911 mg of K2CO3.
Acceptance criteria: NMT 2.5%
Packaging and Storage: Preserve in well-closed containers.
