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

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 120-125 °C for 5 h.
ASSAY
Dissolve
0.500 g in 50 ml of carbon dioxide-free water. Carry out a potentiometric
titration, using 1 M hydrochloric acid . Read the volume added at the 2nd
point of inflexion.
1 ml of 1 M hydrochloric acid
is equivalent to 69.1 mg of K2CO3.

Potassium Carbonate contains not less than 99.5 percent and not more than 100.5 percent of K2CO3, calculated on the dried basis.
Identification— It responds to the tests for
Potassium and for Carbonate.
Loss on
drying— Dry it at 180 for 4 hours: it loses not more than 0.5% of its
weight.
Insoluble substances— Dissolve 1 g in 20 mL of water: the solution is
complete, clear, and colorless.
Heavy
metals— Dissolve 4.0 g in 10 mL of water, add 15 mL of 3 N hydrochloric
acid, and heat to boiling. Add 1 drop of phenolphthalein TS, and neutralize with
1 N sodium hydroxide until the solution is faintly pink in color. Cool, and
dilute with water to 25 mL: the limit is 0.0005%.
Assay— Transfer the dried potassium carbonate obtained in the test for
Loss on
drying to a flask with the aid of 150 mL of water, add 4 drops of methyl
orange TS, and titrate with 1 N hydrochloric acid VS. Each mL of 1 N
hydrochloric acid is equivalent to 69.11 mg of K2CO3.

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 25° 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%.
