Sodium Thiosulphate was originally called Hyposulphite of Soda and Hypo is simply the short form of this common name with is still in use.
The origin of this term is uncertain; these are just deductions.
Hypo is the Greek word for 'under' and if you take a look at the structure of sodium hyposulphate you will note that the sulphite ion (SO3-2) is bonded to a sulphur atom ( as in replacing an oxygen atom of SO4-2 with a sulphur atom- thiosuphate). For purpose of symmetry, the structure of thiosulphate is drawn with the sulphur on top and the sulphite 'under' the sulphur. Hence the term hypo.
It has applications in photographic processing and so does sodium carbonate (called washing soda), hence the term soda.
What else can I help you with?
Does chlorine react with hypo?
It reacts with water and a base called a hot aqueous alkali.
How do you prepare hypo solution?
To prepare a hypo solution, dissolve sodium thiosulfate in water in a ratio of 1 part sodium thiosulfate to 5 parts water. Stir until completely dissolved. This solution is commonly used in photography to stop the development process.
What are the three components in order of administration used to treat cyanide exposure?
Amyl nitrite, sodium nitrite, sodium thiosulfate
What is the procedure for the standardization of sodium thiosulfate?
Thiosulfate can be standardised by adding excess potassium iodide solution to a known volume of a standard acidified solution of potassium dichromate, and then titrating the liberated iodine against the sodium thiosulfate solution.http://www.meduniv.lviv.ua/files/kafedry/tokshim/English/Analytical/Manuals_Analytchem/Iodometry.pdf
What solution is produced when water and sodium thiosulfate will mixed?
A solution of sodium thiosulfate is produced.
Does chlorine react with hypo?
It reacts with water and a base called a hot aqueous alkali.
What is sodium thiosulphates chemical symbol?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
Why sodium thiosulphate is called hypo?
Sodium thiosulfate is called hypo because it was historically used as a photographic fixer, which removed unexposed silver halide from photographic film. The term "hypo" is short for "hypo-sulfite," indicating its chemical composition.
What is the scientific name of sodium thiosulfate?
A white, translucent crystalline compound, Na2S2O3·5H2O, used as a photographic fixing agent and as a bleach. Also called hypo, hyposulfite; Also called sodium hyposulfite. Source: http://www.answers.com/sodium+thiosulfate?gwp=11&ver=2.3.0.609&method=3
Why Na2S2O3.5H2O is known as Hypo?
Sodium Thiosulphate was originally called Hyposulphite of Soda and Hypo is simply the short form of this common name still in use. The origin of this term is uncertain.

What is equivalent weight of hypo?
The equivalent weight of sodium thiosulfate (hypo) is 49.05 g/mol. It is calculated as the molar mass divided by the number of equivalents of the species involved in the reaction with the analyte.

What is hypo solution used in chemistry for iodometric titration?
Hypo solution, also known as sodium thiosulfate solution, is commonly used in chemistry for iodometric titrations as a titrant to react with excess iodine after the reaction with the analyte. It is used to neutralize the excess iodine to determine the amount of analyte present in the sample.
Is their any sodium mono sulfate?
No. There is no such compound. Apart from sodium sulphate, there is Sodium thiosulfate.Sodium thiosulfate (Na2S2O3)s a colorless crystalline compound that is more familiar as the pentahydrate, Na2S2O3•5H2O, an efflorescent, monoclinic crystalline substance also called sodium hyposulfite or "hypo.
