The correct Answer is:
To solve the given question, we will analyze both statements one by one and determine their validity. ### Step-by-Step Solution: 1. **Analyze Statement 1**: - The statement claims that an aqueous solution of hydrogen peroxide is kept in a glass or metal container containing some urea or phosphoric acid. - **Fact Check**: Hydrogen peroxide (H2O2) is known to decompose over time, especially when exposed to light and certain materials. - **Conclusion**: It cannot be stored in glass containers because the rough surface of glass can contain alkali oxides, which catalyze the decomposition of hydrogen peroxide. Therefore, this statement is incorrect. 2. **Analyze Statement 2**: - The statement claims that urea or phosphoric acid acts as a negative catalyst for the decomposition of hydrogen peroxide. - **Definition of Negative Catalyst**: A negative catalyst, or inhibitor, is a substance that slows down or retards the rate of a chemical reaction. - **Fact Check**: Urea and phosphoric acid are known to act as stabilizers for hydrogen peroxide, thereby decreasing the rate of its decomposition. - **Conclusion**: This statement is correct. 3. **Final Evaluation**: - Statement 1 is false because hydrogen peroxide should not be stored in glass or metal containers due to decomposition risks. - Statement 2 is true because urea and phosphoric acid serve as negative catalysts, stabilizing hydrogen peroxide. ### Final Answer: - Statement 1 is false. - Statement 2 is true.
