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
What three medications are used in the treatment for cyanide exposure?
Several antidotes are: sodium nitrite, sodium thiosulfate, hydroxocobalamin.
How can i determine the available chlorine in Sodium hypochlorite (Bleach) by titration with Sodium Thiosulfate?
To determine the available chlorine in sodium hypochlorite (bleach) using titration with sodium thiosulfate, first, dilute the bleach sample and then add an excess of potassium iodide, which reacts with the chlorine to form iodine. Next, titrate the liberated iodine with a sodium thiosulfate solution until a faint yellow color disappears, indicating that all iodine has reacted. The endpoint can be further refined with starch indicator, which changes color when iodine is fully reduced. Finally, calculate the available chlorine concentration based on the volume of sodium thiosulfate used in the titration.
How do you check calcium hypochlorite purity?
To check the purity of calcium hypochlorite, you can perform a titration method using sodium thiosulfate. First, dissolve a known quantity of calcium hypochlorite in water, then add an excess of potassium iodide, which will react with the available chlorine to produce iodine. Titrate the released iodine with sodium thiosulfate until the solution turns from brown to colorless. The amount of sodium thiosulfate used can be used to calculate the purity based on the chlorine content present in the sample.
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.
What are the three components in order of administration used to treat cyanide exposure?
Amyl nitrite, sodium nitrite, sodium thiosulfate
What chemical used as a'fixer' in photography?
Either ammonium thiosulfate (the best to use) or sodium thiosulfate.
What is used to preserve sodium thiosulfate?
Sodium thiosulfate is typically preserved with an inert gas such as nitrogen or argon to prevent oxidation and degradation. It is important to store sodium thiosulfate in a tightly sealed container away from light and moisture to maintain its stability and effectiveness.
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.
How is used Sodium thiosulfate in chlorine removal shampoo?
Sodium thiosulfate is used in chlorine removal shampoos because it has a chemical property that allows it to neutralize chlorine. Chlorine can damage hair by stripping it of its natural oils and causing dryness. By adding sodium thiosulfate to shampoo, it can help to break down and remove chlorine from the hair, leaving it clean and less damaged.
Is sodium thiosulfate basic?
Sodium thiosulfate is not a base; it is a neutral compound with a pH close to 7. It is often used as an antidote for cyanide poisoning and as a fixer in photography.
What chemical is used to bring up the pH in swimming pool?
sodium thiosulfate
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
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
Is sodium thiosulfate an oxidizer?
Sodium thiosulfate is not an oxidizer; it is commonly used as a reducing agent. It is often used to neutralize the effects of oxidizing agents in chemical reactions or to remove excess chlorine in water treatment.

What is the difference between anhydrous sodium thiosulphate and sodium thiosulphate?
None. Anhydrous simply means ..... (not in solution). The opposite is aqueous (in solution).Added:..... crystalised without hydrate in the solid crystals.mono-hydrate means it is crystallised with 1 (one) molecule H2O per molecule salt.CuSO4.5H2O means : penta-hydrate of copper sulfate
