How do you prepare N 80 thiosulphate?
To prepare N 80 thiosulfate, dissolve 80 grams of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in enough distilled water to make a final volume of 1 liter. Stir the solution until the thiosulfate is completely dissolved. Ensure that the solution is mixed well and store it in a properly labeled container. Always follow safety protocols when handling chemicals.

How do you prepare 0.1N Na2S2O3 solution?
To prepare a 0.1N Na2S2O3 solution, dissolve 24.98 grams of Na2S2O3·5H2O (sodium thiosulfate pentahydrate) in distilled water and dilute to 1 liter in a volumetric flask. This will give you a 0.1N (normal) solution of Na2S2O3.
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.
How would you prepare 1L of 000100 M Na2S2O3 starting with solid Na2S2O3 The numbers in Na2S2O3 are subscripts.?
first we calculate the molecular weight M.W=158.11 mass of Na2S2O3=M.W*concentration*volume(in litter) for a concentration of 0.001 mass of Na2S2O3=158.11*0.001*1=0.15811 g so we use this mass and continue the volume to be 1 L
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.
What is the formula for the sodium thiosulfate?
Na2S2O3
What does na2s2o3 STANDS FOR?
Sodium thiosulfate
