Muby Chemicals, established in 1976, is
the pioneer manufacturer of Sodium Thiosulphate and
various other chemicals in
India. Mubychem Group
has several manufacturing facilities spread across
Western India. Muby chemicals know about Sodium
Thiosulphate better than any other vendor in the world.
Sodium thiosulphate (Na2S2O3),
also spelled Sodium thiosulfate, is a colorless crystalline compound
that is more familiar as the pentahydrate, Na2S2O3•5H2O.
It
is
an efflorescent, monoclinic crystalline substance also called sodium
hyposulfite or “hypo.”
The thiosulphate anion is tetrahedral in shape and is
notionally derived by replacing one of the oxygen atoms by a sulphur atom in
a sulphate anion. The S-S distance indicates a single bond, implying that the
sulphur bears significant negative charge and the S-O interactions have more
double bond character. The first protonation of thiosulphate occurs at
sulphur.
Thiosulphate anion characteristically reacts with dilute
acids to produce sulphur, sulphur dioxide and water
Na2S2O3
+ 2HCl → 2NaCl + S + SO2 + H2O
This reaction is known as a clock reaction, because when
the sulphur reaches a certain concentration the solution turns from
colourless to a pale yellow. This reaction has been employed to generate
colloidal sulphur. When the protonation is conducted at low temperatures, H2S2O3
(thiosulphuric acid) can be obtained. It is a strong acid pKa

IT IS NICE TO BE IMPORTANT BUT ….... BUT
IT IS MORE IMPORTANT TO BE NICE
Refresh Yourself with these pleasant
thoughts.
I shall pass through this world, but once. If therefore, there is any good
that I can do, or if there is any favour that I can show to a fellow human
being, let me do it now. Let me not defer or neglect it. For I shall not
tread this way again.
IT IS NICE TO BE IMPORTANT BUT ….... BUT IT IS MORE IMPORTANT
TO BE NICE
If I give you “My Word”
Nobody can undo it. If I sign an “Agreement” my Lawyer will undo it
Wise men never sit
and cry over their loss. But work on to redress the same.

Uses of Sodium Thiosulfate
Pentahydrate or Sodium Thiosulphate Pentahydrate
Sodium thiosulphate 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 thiosulphate 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.
