Want this question answered?
stanaderised of Na2S2O3 .
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
Na2S2O3 oxidation number
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)
Oxidation no of sulphur is +2.
Formula: Na2S2O3
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
Sodium Thiosulphate is Na2S2O3 and water is H2O.

why flask keep in dark during standardization of na2s2o3 using k2cr2o7
