Contains
not less than 99.0 percent and not more than 100.5 percent of Na2S2O3,
calculated on the anhydrous basis.
Packaging and storage— Preserve in tight containers.
Identification—
A: To a solution (1 in
10) add a few drops of iodine TS: the color is discharged.
B: A solution (1 in 10)
responds to the tests for Sodium and for Thiosulfate.
Water— Dry about 1.0 g,
accurately weighed, in vacuum at 40 o to 45o for 16 hours:
it loses between 32.0% and 37.0%
of its weight.
Calcium— Dissolve 1 g Sodium Thiosulfate in 20 mL of water, and add a few mL of ammonium oxalate TS: no turbidity is produced.
Heavy metals—: the
limit is 0.002%.

DEFINITION
Content
99.0 per cent to 101.0 per cent of Na2S2O3,5H2O.
CHARACTERS
Appearance
Transparent, colourless crystals, efflorescent in dry air.
Solubility
Very soluble in water, practically insoluble in ethanol 96 per cent. It
dissolves in its water of crystallization at about 49 °C.
IDENTIFICATION
A.
It decolorizes iodinated potassium iodide solution.
B.
To 0.5 ml of solution S (see Tests) add 0.5 ml of water R and 2 ml of silver nitrate solution. A white precipitate is formed which rapidly becomes
yellowish and then black.
C.
To 2.5 ml of solution S add 2.5 ml of water and 1 ml of hydrochloric
acid. A precipitate of sulphur is formed and gas is evolved which gives a blue colour to starch iodate paper.
D.
1 ml of solution S gives reaction of sodium.
TESTS
Solution S
Dissolve 10.0 g in
carbon
dioxide-free water R prepared from distilled water R and dilute to
100 ml with the same solvent.
Appearance of solution
The freshly prepared solution
is clear and colourless.
Dissolve 10.0 g in 50 ml of
distilled water, add 1 ml of 0.1 M sodium hydroxide and dilute to 100
ml with the same solvent.
pH
6.0 to 8.4 for the freshly
prepared solution S.
Sulphates and sulphites
Maximum 0.2 per cent.
Sulphides
To 10 ml of solution S add
0.05 ml of a freshly prepared 50 g/l solution of sodium nitroprusside. The
solution does not become violet.
Heavy metals
Maximum 10 ppm.
ASSAY
Dissolve Sodium Thiosulfate 0.500 g in 20 ml of
water and titrate with 0.05 M iodine, using 1 ml of starch solution,
added towards
the end of the titration, as indicator.
1 ml of 0.05 M iodine
is equivalent to 24.82 mg of Na2S2O3,5H2O.

DESCRIPTION
Sodium
Thiosulfate or Sodium Thiosulphate occurs as
large, colorless crystals or as a coarse, crystalline powder. It is deliquescent
in moist air and effloresces in dry air at a temperature above 33°. Its
solutions are neutral or faintly alkaline to litmus. One gram dissolves in 0.5 mL of water. It is insoluble in alcohol.
Function: Sequestrant;
antioxidant.
REQUIREMENTS
Identification
A. Add a few drops of iodine
TS to a 1:10 aqueous solution. The color disappears.
B. A 1:20 aqueous solution
gives positive tests for Sodium and for Thiosulfate.
Assay: Not less than
99.0% and not more than 100.5% of Na2S2O3 after drying.
Lead: Not more than 2
mg/kg.
Selenium: Not more than
0.003%.
Water: Between 32.0% and
37.0%.
