उत्तर

Na2S2O3

Oxidation number of Na = +1

Oxidation number of O = –2

Na2S2O3 is a neutral molecule.

∴ Sum of the oxidation numbers of all atoms = 0

∴ 2 × (Oxidation number of Na) + 2 × (Oxidation number of S) + 3 × (Oxidation number of O) = 0

∴ 2 × (+1) + 2 × (Oxidation number of S) + 3 × (–2) = 0

∴ 2 × (Oxidation number of S) + 2 − 6 = 0

∴ 2 × (Oxidation number of S) = + 4

∴ Oxidation number of S = `+4/2`

∴ Oxidation number of S in Na2S2O3 = +2
