Which of the following chemical species contain at least one element exhibiting an actual oxidation — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

In $C_3O_2$ ($O=C=C=C=O$), the central carbon is bonded only to identical carbons and has an O.S. of 0. In $S_4O_6^{2-}$, the two central sulphur atoms are bonded only to other sulphurs, giving an O.S. of 0. $Br_3O_8$ has +6, +4, +6 states. Bleaching powder has Cl in -1 and +1 states.
