The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Statement 1**: - The first statement states that hydrogen peroxide (H₂O₂) is stored in wax-lined glass. This is important because H₂O₂ is a sensitive compound that can decompose easily under certain conditions. 2. **Understanding Statement 2**: - The second statement explains that traces of alkali metal ions in the glass can catalyze the decomposition of H₂O₂. This means that if alkali metal ions (like sodium or potassium) are present, they can speed up the breakdown of hydrogen peroxide into water and oxygen. 3. **Analyzing the Decomposition of H₂O₂**: - Hydrogen peroxide decomposes into water (H₂O) and oxygen (O₂) when it breaks down. This reaction can be accelerated by the presence of catalysts, including alkali metal ions. 4. **Conclusion on Statement Validity**: - Since H₂O₂ is prone to decomposition, it is stored in wax-lined glass to prevent the influence of alkali metal ions that could catalyze this decomposition. Therefore, both statements are correct: - Statement 1 is true: H₂O₂ is stored in wax-lined glass. - Statement 2 is true: Alkali metal ions catalyze the decomposition of H₂O₂. 5. **Final Answer**: - Both statements are correct, and the reason provided in Statement 2 correctly explains the assertion in Statement 1.
