What happens when `H_2S` reacts with `SO_2` ?

Explanation

To understand what happens when \( H_2S \) reacts with \( SO_2 \), we will analyze the reaction step by step.

### Step 1: Identify the Reactants and Their Oxidation States
- The reactants are hydrogen sulfide (\( H_2S \)) and sulfur dioxide (\( SO_2 \)).
- In \( H_2S \), sulfur has an oxidation state of \(-2\).
- In \( SO_2 \), sulfur has an oxidation state of \(+4\).
