**Question 25** *Which is the oxidizing agent in the reaction below?* \[ \text{Cr}_2\text{O}_7^{2-} + 6 \text{S}_2\text{O}_3^{2-} + 14 \text{H}^+ \rightarrow 2 \text{Cr}^{3+} + 3 \text{S}_4\text{O}_6^{2-} + 7 \text{H}_2\text{O} \] 1. ⃝ Cr\(_2\)O\(_7^{2-}\) 2. ⃝ S\(_2\)O\(_3^{2-}\) 3. ⃝ S\(_4\)O\(_6^{2-}\) 4. ⃝ H\(^+\) **Explanation:** In the given reaction: - Cr\(_2\)O\(_7^{2-}\) (dichromate ion) - S\(_2\)O\(_3^{2-}\) (thiosulfate ion) - H\(^+\) (proton) The products are: - Cr\(^{3+}\) (chromium(III) ion) - S\(_4\)O\(_6^{2-}\) (tetrathionate ion) - H\(_2\)O (water) To identify the oxidizing agent, we need to determine which species is being reduced. The oxidizing agent is the species that gains electrons. 1. Cr\(_2\)O\(_7^{2-}\) is reduced to Cr\(^{3+}\), since chromium goes from an oxidation state of +6 in Cr\(_2\)O\(_7^{2-}\) to +3 in Cr\(^{3+}\). 2. S\(_2\)O\(_3^{2-}\) is oxidized to S\(_4\)O\(_6^{2-}\). 3. H\(^+\) remains as H\(^+\) in this context. Therefore, the oxidizing agent in this reaction is Cr\(_2\)O\(_7^{2-}\).
