C. The
solution prepared for identification test A gives reaction of sodium.
TESTS
Solution S
Dissolve
5.0 g in portions in a mixture of 5 ml of hydrochloric acid and 25 ml of
distilled water. Heat the solution to boiling and cool. Add dilute
sodium hydroxide solution until the solution is neutral and dilute to 50 ml

solution is clear and not more intensely coloured than reference.
Dissolve
4.0 g in 10 ml of water.
Alkali
hydroxides and bicarbonates
Dissolve 1.0 g in 20 ml of water, add 20 ml of
barium chloride solution and filter. To 10 ml of
the filtrate add 0.1 ml of phenolphthalein solution. The solution does
not become red. Heat the remainder of the filtrate to boiling for 2 min. The
solution remains clear.

ASSAY
Dissolve
2.000 g in 25 ml of water. Titrate with 1 M hydrochloric acid,
using 0.2 ml of methyl
orange solution R as indicator. 1 ml of 1 M hydrochloric acid
is equivalent to 52.99 mg of Na2CO3.

Carbonic
acid, disodium salt.
Disodium carbonate [CAS 497-19-8]
Monohydrate 124.00
[CAS 5968-11-6]
It is anhydrous or contains one molecule of water of hydration. It contains not less than 99.5 percent and not more than 100.5 percent of Na2CO3, calculated on the anhydrous basis.
Identification— It responds to the tests for
Sodium 191 and for Carbonate.
Water—
Dry about 2 g, accurately weighed, at 105 for 4 hours: the anhydrous form
loses not more than 0.5%, and the hydrous form between 12.0% and 15.0%, of its
weight.
Heavy
metals—the limit is 0.001%.
Assay—
Transfer the anhydrous substance obtained in the test for Water
to a flask with the aid of 50 mL of water, add methyl red TS, and titrate
with 1 N sulfuric acid VS. Add the acid slowly, with constant stirring, until
the solution becomes faintly pink. Heat the solution to boiling, cool, and
continue the titration. Heat again to boiling, and titrate further as necessary
until the faint pink color is no longer affected by continued boiling. Each mL
of 1 N sulfuric acid is equivalent to 52.99 mg of Na2CO3.
