What is sodium thiosulphates chemical symbol?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
What is the chemical symbol for sodium thiosulphate?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
What is the use of Sodium thiosulphate in iodometry?
In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
Why do you use starch to standardise sodium thiosulphate using potassium iodate?
Starch acts as an indicator for the endpoint of the reaction between sodium thiosulphate and potassium iodate, as it forms a blue-black complex with iodine. This color change helps identify when all the iodine has been liberated from the reaction. This method is commonly used in titrations to determine the concentration of the sodium thiosulphate solution accurately.
What is the compound symbol of sodium bicarbonate?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O. Hope that helps.

Why sodium thiosulfate is known as hypo?
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.

Why is hypo used in photography?
Hypo, or sodium thiosulfate, is used in photography to fix or stabilize the image on photographic paper by removing any unexposed silver halide. This process helps to make the image permanent and prevent further exposure to light from affecting the final print.
What color is Sodium Thiosulphate?
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
Why use sodium Bicarbonate for titration of sodium thiosulphate using pottasium dicromate?
because sodium thiosulphate is unstable and iodine also so to maintain neutral medium we have to use sodiumcarboate
What is a bromin?
Sodium thiosulphate solution (5-25 %)
What is the boiling point of sodium thiosulphate?
The boiling point of sodium thiosulphate is 100 degrees Celsius, the same as water.That would be 212 degrees Fahrenheit.
Indicator used during the standardization of sodium thiosulphate?
Starch
The hypo solution used in photography is the aqueous solution of?
Sodium thiosulphate (sulphate contains 4 oxygen atoms, thio-sulphate has one of these replaced by a sulphur atom). Dissolves away unexposed silver salts from photographic film or paper.
