H(2)S acts only as reducing agent while ...

`H_(2)S` acts only as reducing agent while `SO_(2)` can act both as a reducing agent and as an oxidising agent. How will you account for it ?

Text Solution

AI Generated Solution

To understand why \( H_2S \) acts only as a reducing agent while \( SO_2 \) can act both as a reducing agent and as an oxidizing agent, we need to analyze the oxidation states of sulfur in both compounds and their respective chemical behaviors. ### Step-by-Step Solution: 1. **Identify the Oxidation States**: - In \( H_2S \) (hydrogen sulfide), sulfur has an oxidation state of -2. - In \( SO_2 \) (sulfur dioxide), sulfur has an oxidation state of +4. ...
