\( \text{O}_3 \) (ozone) is a strong oxidizing agent, while \( \text{H}_2\text{O}_2 \) (hydrogen peroxide) is a powerful oxidizer as well, but not as strong as ozone.
Both substances can react with reductants, but to differentiate them, we would focus on their reaction with oxidants, where ozone shows more aggressive oxidizing behavior.
Additionally, ozone is more reactive than hydrogen peroxide and can be distinguished by observing its reactions in different oxidative conditions.
