Muby Chemicals, established in 1976, is
the pioneer manufacturer of Sodium Thiosulfate Pentahydrate or Sodium Thiosulphate
Pentahydrate and
various other chemicals in India. Mubychem Group
has several manufacturing facilities spread across
Western India. Muby chemicals know about Sodium
Thiosulfate Pentahydrate or Sodium Thiosulphate Pentahydrate, better than any other vendor in the world.
Sodium Thiosulfate Pentahydrate (Na2S2O3),
also spelled Sodium Thiosulphate Pentahydrate, is a colorless crystalline compound
that is more familiar as the pentahydrate, Na2S2O3•5H2O.
It
is
an efflorescent, monoclinic crystalline substance also called Sodium Hyposulphite or “Hypo.”
The thiosulfate anion is tetrahedral in shape and is
notionally derived by replacing one of the oxygen atoms by a sulfur atom in
a sulfate anion. The S-S distance indicates a single bond, implying that the
thiosulfate bears significant negative charge and the S-O interactions have more
double bond character. The first protonation of thiosulfate occurs at
sulphur.

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%.
We can give both the grades Pentahydrate and Anhydrous.
We can give the technical grade small crystals and large crystals too.
We offer
Sodium Thiosulphate IP, Sodium Thiosulphate BP, Sodium Thiosulfate USP, and
Sodium Thiosulfate Extra Pure from our world class FDA approved, ISO-9001-2008 Certified facility, Anmol Chemicals

Uses of Sodium Thiosulfate
Pentahydrate or Sodium Thiosulphate Pentahydrate
Sodium thiosulfate is used in
Iodometry.
It is used for Gold
Extraction.
It is used in Analytical
Chemistry.
It is an antitode to Cyanide
poisioning.
It is a component in hand warmers and
other chemical heating pads that produce heat by exothermic
crystallization of a super cooled solution.
Sodium thiosulphate is used in Bleach.
In pH testing of bleach
substances.
To de-chlorinate tap water for
aquariums or treat effluent from waste water treatments prior to release
into rivers. The
amount of Sodium thiosulfate required can vary with the pH of the
water. A range of approximately 2 to 7 parts sodium thiosulfate to
neutralize one part chlorine is generally suggested. To
neutralize 1 liter of a 200 ppm chlorine solution, approximately 0.4 -
1.4 grams of sodium thiosulfate would be required.
It is used to lower chlorine levels in
swimming pools and spas following super chlorination.
It is used to remove iodine stains, e.g.
after the explosion of nitrogen triiodide.
Sodium thiosulfate is used in bacteriological water
assessment.
It is used in the tanning of leather.
Melted sodium thiosulfate is very easy
to overcool to room temperature and when crystallization is forced, the
sudden temperature jump to 48.3°C can be experienced by touch. It is
used in phase change material.
It is used in paper industry.
It is used in medicine and as disinfectant.
A low amount can be found in natural hot springs water, but
they do have trace sodium sulfide too, which is why it can used to treat
skin problems and some bathe in it to relieve them of skin problems,
rheumatism, although indirectly. It is
systemically for cyanide or arsenic poisoning and topically as an
antifungal.
It is used in electroplating.
As part of patina recipes for
copper alloys.
Often used in pharmaceutical
preparations as an anionic surfactant to aid in dispersion.
