What is the formula for sodium thiosulfate?
Na2S2O3
Sodium thiosulfate/Formula
An inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio. Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na2S2O3. xH2O. Typically it is available as the white or colorless pentahydrate, Na2S2O3·5H2O.
How can we prepare 0.1 normal sodium thiosulphate?
Preparation of 0.1N Sodium thiosulphate Dissolve 24.8g of sodium thiosulphate pentahydrate(Na2S2O3. 5H2O) in 800 ml of freshly boiled and cooled water and mix thoroughly by shaking for approximately 15 minutes.

How is sodium thiosulfate prepared from sodium sulphite?
Method of prepration of sodium thiosulphate In the laboratory, this salt can be prepared by heating an aqueous solution of sodium sulphite with sulphur or by boiling aqueous NaOH and sulfur according to this equation: 6 NaOH + 4 S 2 Na2S + Na2S2O3 + 3 H2O.
What is the order of the sodium thiosulfate?
At lower concentrations, the reaction appears to be closer to 3/2-order in sodium thiosulfate and 1/2- order in hydrochloric acid. The reaction time is more difficult to measure at lower concentrations because the onset of turbidity is more gradual.
What is hypo give any one preparation method?
Sodium thiosulfate is an important inorganic salt with several medical uses. It is also called sodium hyposulfite or ‘hypo’. Preparation: Sodium thiosulfate can be prepared by heating sulfur with either aqueous sodium sulfite solution or aqueous sodium hydroxide solution.
What is sodium thiosulfate used for?
What Is Sodium Thiosulfate Used For and How Does it Work? Sodium thiosulfate is used to treat cyanide poisoning. It is also used to reduce the side effects of the cancer medication cisplatin.
Why sodium carbonate is added to the preparation of sodium thiosulphate?
1. Thiosulfate is unstable under acidic pH conditions, causing the thiosulfate to decompose into sulfur dioxide, elemental sulfur, and water. So, sodium carbonate can be used either to stabilize thiosulfate, or to lower its reaction rate with anything else that it’s been combined with.
