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 are the three components in order of administration used to treat cyanide exposure?
Amyl nitrite, sodium nitrite, sodium thiosulfate
Why na2s2o3 is standerdized?
Sodium thiosulfate (Na2S2O3) is standardized because its concentration needs to be accurately known in order to carry out precise volumetric analyses or titrations. Standardization ensures that the exact concentration of sodium thiosulfate solution is known, thus allowing for accurate measurements and calculations in various chemical reactions and experiments.
What solution is produced when water and sodium thiosulfate will mixed?
A solution of sodium thiosulfate is produced.
What is the valency of sodium thiosulphate?
The valency of sodium thiosulfate is determined by breaking down the compound into its constituent ions. In this case, sodium has a valency of +1 (Na+), and thiosulfate has a total charge of -2 (S2O3^2-). Therefore, the valency of sodium thiosulfate is +1 because it has one sodium ion for every thiosulfate ion in the compound.
How many atoms are in the molecule of sodium thiosulfate?
The molecule of sodium thiosulfate, Na2S2O3, contains 9 atoms in total.
How many moles of Na2S2O3 react with one mole of KClO3 used in the standardization?
Standardization of sodium thiosulfate uses potassium iodate with excess potassium iodide and acidified. Iodine is liberated and that is titrated with sodium thiosulfate. KIO3 + 5KI + 3H2SO4 -----> 3K2SO4 + 3H2O + 3 I2 I2 + 2Na2S2O3 -------> 2NaI + Na2S4O6 So 1 mole of KIO3 produces 3 moles of Iodine. 1 moles of iodine reacts with 2 moles of thiosulfate. So 6 moles of sodium thiosulfate react with 1 mole of potassium iodate KIO3.

Why you add starch indicator in standardization of hyposolution?
Starch indicator is added during the standardization of hypo solution (sodium thiosulfate) to visually signal the endpoint of the titration. When iodine is present, it forms a blue complex with starch, indicating excess iodine. As sodium thiosulfate is added and reacts with iodine, the blue color disappears, signaling that all the iodine has reacted. This color change provides a clear and distinct endpoint for accurate titration results.

Why do you need to do a standardization on a known concentration sodium thiosulphate solution?
Standardization of a known concentration sodium thiosulfate solution is necessary to accurately determine its exact concentration. This process helps to correct for any variations in concentration that may have occurred during preparation or storage, ensuring that precise measurements can be made in subsequent experiments or analyses.
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
What is the reaction of sodium sulphite and sulphur?
When sodium sulfite reacts with sulfur, it forms sodium thiosulfate. This reaction typically involves the oxidation of sodium sulfite by sulfur to produce sodium thiosulfate.
Reaction of bromine with sodium thiosulfate?
When bromine reacts with sodium thiosulfate, it undergoes a redox reaction where bromine is reduced to bromide ions and thiosulfate is oxidized to form sulfate ions. The reaction can be used to titrate bromine in solution, as thiosulfate acts as a reducing agent, consuming the bromine until all the thiosulfate is oxidized.
What happens when sodium thiosulfate dissolves in water?
When water is mixed with sodium thiosulfate the surrounding area temperature decreases causing the temperature to become, colder. for example; the water is at 22.5 C when you mix it with sodium thiosulfate the temperature could decrease up to 19.5 C this is because sodium thiosulfate an endothermic reaction which makes new bonds with the water and the sodium thiosulfate
