The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement independently and determine their validity. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - Statement: "Nessler's reagent gives a brown precipitate with aqueous ammonia as well as with ammonium salts." - Nessler's reagent is chemically represented as \( K_2HgI_4 \). - Aqueous ammonia (NH₃) can react with ammonium ions (NH₄⁺) present in ammonium salts. - When ammonium ions react with Nessler's reagent in the presence of hydroxide ions (OH⁻), it forms a brown precipitate of \( Hg_2(OH)ClNH_2I \). - Therefore, Statement 1 is **True**. 2. **Understanding Statement 2**: - Statement: "Aqueous ammonia gives a brown precipitate with a solution of manganese (II) chloride and hydrogen peroxide." - Aqueous ammonia (NH₄OH) reacts with manganese (II) chloride (MnCl₂) to form manganese hydroxide (Mn(OH)₂), which is a white precipitate. - When hydrogen peroxide (H₂O₂), an oxidizing agent, is added, it oxidizes Mn(OH)₂ to form a brown precipitate of manganese oxide (MnO₂). - Therefore, Statement 2 is also **True**. 3. **Relationship Between Statements**: - Both statements are true independently, but they do not explain or relate to each other. - Statement 1 discusses the reaction of Nessler's reagent with ammonia and ammonium salts, while Statement 2 discusses the reaction of aqueous ammonia with manganese (II) chloride and hydrogen peroxide. 4. **Conclusion**: - Both statements are true, but Statement 2 does not serve as an explanation for Statement 1. - The correct answer is that both statements are true, but Statement 2 is not the correct explanation of Statement 1. ### Final Answer: - Both statements are true, but Statement 2 is not the correct explanation of Statement 1.
