Sodium Thiosulfate USP

Na2S2O3·5H2O 248.19

Sodium Thiosulfate 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—

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%.

Sodium Thiosulphate BP

Na2S2O3,5H2O

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.

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.
