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
What is the structure of NA2S2O3?
stanaderised of 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 mass of na2s2o3 5h2o is needed to prepare 500.00 ml of 0.1000 m na2s2o3?
Mol.Wt =248.17Molarity =( Wt/ Mol.Wt ) /No:of litres of solution0.1 =( Wt / 248.17) / 0.5Wt =0.1 *0.5*248.17Wt = 12.4085g in 500ml of solution.
What are the oxidation numbers for the elements in Na2S2O3?
Na2S2O3 oxidation number
What is hypo solution used in chemistry for iodometric titration?
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
What is 2334 divided by 0002?
1167
What is the formula for the sodium thiosulfate?
Na2S2O3
What is the oxidation no Of S In Na2S2O3?
+2
What does na2s2o3 STANDS FOR?
Sodium thiosulfate
What is the product of Na2S2O3 HCl?
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)
What is 0002?
a number
