To prepare a 250 ml saturated solution of sodium thiosulphate, start by adding sodium thiosulphate (Na2S2O3·5H2O) to a clean container, gradually mixing it with distilled water until no more solid dissolves and the solution reaches saturation. Typically, this requires adding approximately 80 grams of sodium thiosulphate to the water. Stir the mixture thoroughly and allow it to settle for any undissolved solids to settle at the bottom. Finally, transfer the clear solution to a volumetric flask and make up the volume to 250 ml with distilled water.

How can you prepare Benedict's solution?
To prepare Benedict's solution, dissolve copper(II) sulfate, sodium citrate, and sodium carbonate in water, then add distilled water to make a final volume. Heat the solution until it boils and let it cool before filtering. Adjust the pH to 12 with sodium hydroxide and store it in a dark bottle.
How do you prepare 1 percent of sodium citrate?
To prepare a 1% solution of sodium citrate, you would mix 1 gram of sodium citrate with 99 grams of water (for a total of 100 grams solution). Stir the mixture until the sodium citrate is fully dissolved in the water.
What is the electricity conductivity of a saturated salt solution?
The electrical conductivity of a saturated salt solution, such as sodium chloride (NaCl) in water, is relatively high due to the presence of a significant concentration of ions. In a saturated solution, the conductivity can vary but typically ranges from 10 to 20 mS/cm, depending on temperature and specific conditions. The ions in the solution, including Na⁺ and Cl⁻, facilitate the flow of electric current, making the solution a good conductor.

How do you ppprepare saturated solution of sodium trioxocarbonate (iv)?
To prepare a saturated solution of sodium trioxocarbonate (IV), simply add the compound to distilled water at room temperature while stirring. Continue adding the compound until no more dissolves, indicating that the solution is saturated. This process ensures that the maximum amount of sodium trioxocarbonate (IV) is dissolved in the water.
Is sodium thiosulphate conductive?
Sodium thiosulfate is not conductive because it does not dissociate into ions in solution. It is a non-electrolyte.

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 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.
