Which of the following equation depicts the oxidizing nature of H 2 O 2 ?
Options
- A2 I - + H 2 O 2 + 2 H + → I 2 + 2 H 2 O
- BI 2 + H 2 O 2 + 2 OH - → 2 I - + 2 H 2 O + O 2
- CCl 2 + H 2 O 2 → 2 HCl + O 2
- DKIO 4 + H 2 O 2 → KIO 3 + H 2 O + O 2
Correct answer
A. 2 I - + H 2 O 2 + 2 H + → I 2 + 2 H 2 O
Step-by-step solution
Oxidizing nature of H2​O2​ means it oxidizes other substance and itself gets reduced. In such reactions O2​ is not evolved. 2 I - + H 2 O 2 + 2 H + → I 2 + 2 H 2 O Oxygen reduces from - 1 to   - 2 So, its reduction will takes place. Hence it will behave as oxidising agent or it shows oxidising nature. While in other option it change from ( - 1 ) to 0 .
