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 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 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
