NaS2 is an unbalanced equation. It would need to be Na2S to be a balanced equation (two sodium, one sulfide). Na2S is Sodium Sulfide.
sodium disulfur trioxide.
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
Antimony sulfide; sodium oxide; carbonic acid.
The molecular mass of sodium thiosulfate heptahydrate is 248,18 g.

IUPAC(international union of pure and applied chemistry)
stanaderised of Na2S2O3 .
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality 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
Sodium thiosulfate
Na2S2O3
+2
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)
why flask keep in dark during standardization of na2s2o3 using k2cr2o7
Formula: Na2S2O3
Tetraiodosilane is the chemistry name for Sil4.
Oxidation no of sulphur is +2.
