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?
To prepare a 0.1N solution of sodium thiosulfate, we need to weigh out 25 grams because each mole of sodium thiosulfate (Na2S2O3) is equivalent to 248.18 grams. Given that the formula weight is known, 25 grams gives the correct molarity of the solution.
What mass of na2s2o3 5h2o is needed to prepare 500.00 ml of 0.1000 m na2s2o3?
To calculate the mass needed, you first need to determine the molar mass of Na2S2O3•5H2O. Then use the formula: mass = molarity (M) x volume (L) x molar mass (g/mol). Substitute the values to find the mass of Na2S2O3•5H2O needed.
What is 2334 divided by 0002?
1167
What is the product of Na2S2O3 HCl?
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)
What is 0002?
a number
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.
Which number is bigger 0.002 or 0.003?
0.003 is bigger, but not by much.
What is the formula for the sodium thiosulfate?
Na2S2O3
What does na2s2o3 STANDS FOR?
Sodium thiosulfate
