The polyatomic anions in sodium sulphate have the formula SO4-2, while the polyatomic anions in sodium thiosulphate have the formula S2O3-2.
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.

Sodium thiosulfate reacts with iodine to form sodium iodide, sodium tetrathionate, and sulfur dioxide. This reaction is often used in titrations to determine the concentration of iodine in a solution.
The boiling point of sodium thiosulphate is 100 degrees Celsius, the same as water.That would be 212 degrees Fahrenheit.
Anhydrous sodium sulphate is Na2SO4
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.
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
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.
Sodium + Sulphate + Water = Sodium Sulphate + Water
because sodium thiosulphate is unstable and iodine also so to maintain neutral medium we have to use sodiumcarboate
