Rohan heard that instructions were given to the laboratory attendent to store a particular chemical, i.e., keep it in the dark room, add some urea in it, and keep it away keep form dust. This chemical acts as an oxidizing as well as a reducing agent in both acidic and alkaline media. This chemical is important for use in the pollution control treatment of domestic and industrial effluents . Identify the compound and why it is stored with precautions.

Explanation

**Step-by-Step Solution:**

1. **Identify the Chemical:**
- The chemical in question is identified as hydrogen peroxide (H₂O₂). This is based on the clues provided in the question that it acts as both an oxidizing and reducing agent in acidic and alkaline media.

2. **Properties of Hydrogen Peroxide:**
- Hydrogen peroxide is known for its dual role as an oxidizing agent and a reducing agent. In acidic conditions, it can oxidize substances, while in alkaline conditions, it can reduce them.

3. **Reasons for Precautions in Storage:**
- Hydrogen peroxide is unstable and can decompose easily. This decomposition can be triggered by exposure to light, heat, or contaminants such as dust.

4. **Decomposition Reaction:**
- The decomposition of hydrogen peroxide can be represented by the following chemical equation:
\[ 2 H₂O₂ \xrightarrow{h\nu} 2 H₂O + O₂ \]
- This reaction shows that hydrogen peroxide breaks down into water and oxygen when exposed to light.

5. **Role of Urea:**
- Urea is added to hydrogen peroxide as a stabilizer. It acts as a negative catalyst, which helps to slow down the decomposition process of hydrogen peroxide, thereby prolonging its shelf life.

6. **Storage Conditions:**
- To prevent decomposition, hydrogen peroxide is stored in dark containers to avoid exposure to light and is kept away from dust and other contaminants.

**Final Conclusion:**
- The compound is hydrogen peroxide (H₂O₂), and it is stored with precautions because it is unstable and can decompose when exposed to light or contaminants. Urea is added to stabilize it and prevent its decomposition.
