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 Wagner react to alkaloid?
Dissolve 2.0 grams of iodine and 6.0 grams of KI in 100.0 ml of H2O.
What is molecular formula of NaS2O3?
The molecular formula of sodium thiosulfate is Na2S2O3.

Will CuCL2 react with Na2S2O3?
Na2S2O3 does react with AgNO3, it is a reaction widely used in non-digital photography. The reaction is: 2AgNO3 + Na2S2O3 = Ag2S2o3 + 2 NaNo3 If hypo is taken in a limited amount, then this happens. The Ag thiosulphate thus formed goes through a change of colour (termed as 'play of colour'). Ag2S2O3 (white) --> yellow --> orange --> brown --> black (AgS ppt). But if hypo is taken in excess amount, then a complex [Ag(S2O3)2]3- , it is readily dissolved in water.

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 does the blank titration use more ns2s2o3?
The blank titration requires more sodium thiosulfate (Na2S2O3) because it compensates for any residual iodine in the reaction mixture that didn't react with the analyte. This residual iodine can interfere with the accuracy of the titration results, so more Na2S2O3 is needed to completely neutralize it.
What is the product of Na2S2O3 HCl?
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)

What does na2s2o3 STANDS FOR?
Sodium thiosulfate
What is the formula for the sodium thiosulfate?

How many milliliters of 0.0200M Na2S2O3 solutions are needed to dissolve 0.450g of AgBr?
To find the amount of Na2S2O3 solution needed, first calculate the moles of AgBr using its molar mass. Then, use the stoichiometry of the balanced equation between AgBr and Na2S2O3 to determine the moles of Na2S2O3 required. Finally, use the molarity of Na2S2O3 to find the volume needed in milliliters.
