Antimony sulfide; sodium oxide; carbonic acid.
Na2S2O3 That's 2 sodiums at 23 each, 2 sulfurs at 32 each, and 3 oxygens at 16 each. 23+23+32+32+16+16+16=158g/mol.
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
The molecular mass of sodium thiosulfate heptahydrate is 248,18 g.
The one that will dissociate into TWO ions is (2) NaBrO3 (sodium bromate). It will dissociate into Na^+ and BrO3^-.
A white, translucent crystalline compound, Na2S2O3·5H2O, used as a photographic fixing agent and as a bleach. Also called hypo, hyposulfite; Also called sodium hyposulfite. Source: http://www.answers.com/sodium+thiosulfate?gwp=11&ver=2.3.0.609&method=3
This compound is sodium thiosulphate. S represents +6 oxidation number.
stanaderised of Na2S2O3 .
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O. Hope that helps.
Na2S2O3 That's 2 sodiums at 23 each, 2 sulfurs at 32 each, and 3 oxygens at 16 each. 23+23+32+32+16+16+16=158g/mol.
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

Sodium thiosulfate
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)
The chemical formula for sodium oxide is Na2O. It is an ionic compound and the ions present are Na+ and O2-.
why flask keep in dark during standardization of na2s2o3 using k2cr2o7
