The reagent(s) that can be used for the oxidation of to is/are: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**(A)** $SO_2 + 2H_2S \rightarrow 3S + 2H_2O$ (Comproportionation). <br>**(B/C)** Strong oxidizing agents that easily convert $S^{2-}$ to $S$. <br>**(D)** $Fe^{3+}$ is reduced to $Fe^{2+}$ while oxidizing $H_2S$ to $S$.
