Incorrect statement:
- H2O2 can act only as an oxidizing agent
Explanation:
- Hydrogen peroxide (H2O2) is a chemical compound that consists of two hydrogen atoms and two oxygen atoms. It is a pale blue liquid, which appears colorless in a dilute form. H2O2 is a versatile compound with several properties and uses.
Properties and Uses of H2O2:
1. Oxidizing and Reducing Agent:
- H2O2 can act both as an oxidizing agent and as a reducing agent, depending on the reaction conditions. As an oxidizing agent, it has the ability to accept electrons from other substances, causing them to be oxidized. On the other hand, as a reducing agent, it can donate electrons to other substances, causing them to be reduced.
2. Decomposition on Exposure to Light:
- H2O2 is unstable and decomposes over time, especially when exposed to light. The decomposition process involves the breaking of the O-O bond, resulting in the formation of water (H2O) and oxygen gas (O2). This decomposition reaction is exothermic and can be catalyzed by various substances such as transition metal ions, alkali metals, and certain enzymes.
3. Storage Requirements:
- H2O2 is typically stored in dark-colored containers, such as plastic or wax-lined glass bottles, to protect it from the detrimental effects of light. Exposure to light can accelerate the decomposition of H2O2, leading to a decrease in its concentration and efficacy. Additionally, it is important to keep H2O2 away from dust or other contaminants that may catalyze its decomposition.
Conclusion:
- Based on the properties and uses of H2O2, the incorrect statement is that it can act only as an oxidizing agent. H2O2 is capable of acting both as an oxidizing agent and as a reducing agent, depending on the reaction conditions.
