The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion (A):** The assertion states that hydrogen peroxide (H₂O₂) is not stored in glass bottles. This is a true statement. 2. **Reasoning Behind the Assertion:** The reason for this assertion is that hydrogen peroxide decomposes when stored in glass bottles. This decomposition is catalyzed by alkali oxides present in the glass. 3. **Composition of Glass:** Glass is primarily composed of silica (SiO₂) and contains alkali metal oxides such as sodium oxide (Na₂O) and calcium oxide (CaO). The presence of these alkali oxides is crucial to understanding the decomposition of H₂O₂. 4. **Decomposition Reaction:** When H₂O₂ comes into contact with alkali oxides, it can decompose into sodium hydroxide (NaOH) and oxygen gas (O₂). The reaction can be represented as: \[ \text{Na}_2\text{O} + \text{H}_2\text{O}_2 \rightarrow \text{NaOH} + \text{O}_2 \] This reaction illustrates how alkali oxides catalyze the breakdown of hydrogen peroxide. 5. **Conclusion:** Since both the assertion and the reason are true, and the reason correctly explains why H₂O₂ is not stored in glass bottles, we can conclude that the correct answer is that both statements are true and the reason is a correct explanation of the assertion. **Final Answer:** Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---
