One should use freshly boiled pure water to prevent oxidation by otherwise present oxygen. After complete solvation of the 'hypo' (more familiar known as the pentahydrate, Na2S2O3•5H2O) the solution should be filtered to after standing overnight to remove sparse sulfur sedimentation.

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.
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 chemical symbol for sodium thiosulphate?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
Could you prepare oxalic acid by adding HCl to a solution of sodium oxalate cooling it to room temp and filtering the resulting mixture?
No we cannot prepare Oxalic acid by the given method. Solubility of Sodium Oxalate is less in comparison to solubility of Oxalic acid. So whatever oxalic acid is formed will remain in the solution and cannot be precipitated out in the form of solid
What is sodium thiosulphates chemical symbol?
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
What is a bromin?
Sodium thiosulphate solution (5-25 %)
How do you prepare 0.01N solution of sodium thiosulphate?
To prepare a 0.01N solution of sodium thiosulfate, dissolve 2.48 grams of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water and make up the solution to 1 liter. This solution will be approximately 0.01N in strength. Remember to accurately weigh the compound and use a volumetric flask for precise dilution.
How do you prepare 0.002m sodium thiosulphate solution?
To prepare a 0.002M sodium thiosulfate solution, dissolve the appropriate amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water to make the desired volume of solution. Calculate the molarity using the formula M = (mol/L) and adjust as needed. Make sure to accurately measure and mix the components to ensure a homogeneous solution.
How do you prepare and standardize of 0.1 N Sodium Thiosulfate solution?
Dissolve 2.48818g of Na2s2o3.5h2o in frishly boiled distilled water. and add 2ml of chloroform for stability, it gives 0.01N sodium thiosulphate sol.
Is sodium thiosulphate conductive?
Sodium thiosulfate is not conductive because it does not dissociate into ions in solution. It is a non-electrolyte.
How do you prepare 0.2M of anhydrous of sodium thiosulphate?
To prepare 0.2M solution of anhydrous sodium thiosulfate (Na2S2O3), you dissolve 24.6g of anhydrous Na2S2O3 in distilled water and dilute it to 1 liter. This is the molar mass method, where molar mass of Na2S2O3 is 158.10 g/mol.
Is sodium thiosulphate soluble?
Yes, sodium thiosulfate is soluble in water. It dissolves readily in water to form a clear solution.

What color is Sodium Thiosulphate?
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
How do you prepare 0.20mol of dc3 of sodium thiosulphate?
Dissolve 31,62 g anhydrous thiosulfate in 1 L demineralized water at 20 oC.
What is the reaction between sodium thiosulphate and iodine?
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.
How can one prepare a saturated sodium bicarbonate solution?
To prepare a saturated sodium bicarbonate solution, add sodium bicarbonate (baking soda) to water until no more can dissolve. This creates a solution where the maximum amount of sodium bicarbonate is dissolved in the water.
