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.
0.1N Sodium Thiosulphate is primary or secondary solutions?
it is a secondary solution because it can change its concentration by absorbing moisture....
How important is standardization in ensuring the accuracy and reliability of a sodium hydroxide solution?
Standardization is crucial in ensuring the accuracy and reliability of a sodium hydroxide solution. It involves calibrating the concentration of the solution against a known standard to ensure consistent and precise results in experiments or processes. This helps maintain the quality and reliability of the solution for various applications.
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 0.02 m sulphuric acid standardization calculation?
To standardize 0.02 M sulfuric acid, you would titrate it against a known concentration of a base, such as sodium hydroxide. By measuring the volume of the base required to neutralize the acid, you can calculate the exact concentration of the sulfuric acid solution. The standardization calculation involves using the stoichiometry of the acid-base reaction to determine the concentration of the acid 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.

Is sodium thiosulphate soluble?
Yes, sodium thiosulfate is soluble in water. It dissolves readily in water to form a clear solution.
Why is sodium thiosulphate used in iodometric titration?
· In analytical chemistry, sodium thiosulphate is used for the determination of the strength of a given solution of iodine. · Sodium thiosulphate is preferred in iodometric analysis due to the fact that sodium thiosulphate is oxidized by iodine. It is also used to determine the strength of many oxidizing agents.
How do you prepare 250ml saturated solution of sodium thiosulphate?
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.
