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.
What is a standard solution?
A standard solution is a solution of known concentration that is used to determine the concentration of an unknown solution in a chemical analysis. It is often prepared by accurately measuring a known amount of solute and dissolving it in a known volume of solvent.

What are the properties of a standard solution?
A standard solution is a solution with a known concentration of a substance. It is typically used in analytical chemistry for calibration and comparison purposes. Standard solutions should be stable, accurately prepared, and have a known concentration that can be used for accurate measurements.

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
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 0.2M 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 are preparations of standard solutions and titrations carried out in industry?
In industry, standard solutions are typically prepared by accurately weighing or measuring a known quantity of a substance and dissolving it in a known volume of solvent. Titrations are carried out by slowly adding the standard solution to the solution being analyzed until the reaction reaches its endpoint, which is indicated by a change in color or conductivity. The volume of the standard solution consumed in the titration allows for calculation of the concentration of the analyte in the original solution.
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.
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.
CHEMICAL KINETICS READINGS BETWEEN Na2S2O3 and HCl?
The reaction between Na2S2O3 and HCl involves the oxidation of thiosulfate ions by hydrogen ions. The rate of the reaction can be determined by measuring the initial rate of the disappearance of thiosulfate ions. The reaction is typically carried out in acidic conditions to provide protons for the oxidation process.
What mass of na2s2o3 5h2o is needed to prepare 500.00 ml of 0.1000 m na2s2o3?

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.
What is the product of Na2S2O3 HCl?
