How does 0.1n na2s2o3 is prepared?
To prepare a 0.1 N (normal) solution of sodium thiosulfate (Na2S2O3), first calculate the required mass of Na2S2O3 based on its equivalent weight. For sodium thiosulfate, the equivalent weight is approximately 126.1 g/mol divided by 2, since it can donate two electrons in redox reactions, resulting in about 63.05 g/equiv. Dissolve the calculated mass of Na2S2O3 in distilled water, then dilute to a final volume of 1 liter. Ensure to mix thoroughly for a homogeneous solution.
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.

Why do you use 25 grams to prepare 0.1N sodium thiosulfate solution?
You do not need especially 25 grams to prepare 1.0 Liter 0.1N Na2S2O3-solution.It depends what substance is used: Na2S2O3 orNa2S2O3•5H2O (more common, called hypo).Molar masses are different, 158.11 g/mol for Na2S2O3 or(158.1 g/mol + 5*18.02 = ) 248.2 g/mol for Na2S2O3•5H2O respectively.To get the 0.10 N solution you'll need 15.8 gram or 24.8 gram respectively, dissolve it togather with 1 gram of disodium carbonate, and add up to 1.0 Liter (freshly boiled) water, let stand overnight and filter on fine grade paper.
How do you 0.02 sodium thiosulfate prepared?
To prepare 0.02M sodium thiosulfate solution, weigh out the required amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) or anhydrous sodium thiosulfate (Na2S2O3). Dissolve this in distilled water and make up the volume to the desired concentration. Make sure to use a volumetric flask for accuracy and precision in preparing the solution.
How do you prepare 0.01N solution of sodium thiosulphate?

How do you prepare 0.01n sodium thiosulfate as per ip?
To prepare 0.01N sodium thiosulfate per Indian Pharmacopoeia (IP) standards, dissolve 25.3 grams of pure sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water to make 1000 ml of solution. This solution will have a normality of 0.01N.
How would the appearance of the solution change for each kinetic trial if the Na2S2O3 solution were omitted from the experiment?
If the Na2S2O3 solution were omitted, the appearance of the solution would not change significantly for each kinetic trial. Na2S2O3 is a reagent that acts as a reducing agent and is not directly involved in the appearance of the reaction solution. Its absence would likely affect the reaction rate rather than the visual appearance of the solution.
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.
