`H_(2) S`

Text Solution

AI Generated Solution

To describe the oxidizing action of \( K_2Cr_2O_7 \) (potassium dichromate) in an acidic medium with \( H_2S \) (hydrogen sulfide), we will follow these steps to derive the balanced ionic equation. ### Step 1: Identify the Oxidation States In \( K_2Cr_2O_7 \), the oxidation state of chromium (Cr) is +6, and in \( H_2S \), the oxidation state of sulfur (S) is -2. During the reaction, chromium will be reduced, and sulfur will be oxidized. ### Step 2: Write the Half-Reactions 1. **Reduction Half-Reaction**: \[ ...
