The correct Answer is:
To solve the question regarding the statements about zinc and copper in the recovery of silver from the complex \([Ag(CN)_{2}]^{-}\), we will analyze both statements step by step. ### Step 1: Analyze Statement 1 **Statement 1**: Zinc and not copper is used in the recovery of silver from the complex \([Ag(CN)_{2}]^{-}\). - **Explanation**: This statement is true. Zinc is indeed used in the recovery of silver from the cyanide complex. The reason for this is that zinc can effectively displace silver from the complex due to its higher reactivity compared to silver. When zinc is added to the solution, it forms zinc cyanide and releases silver in its metallic form. ### Step 2: Analyze Statement 2 **Statement 2**: Zinc is a more powerful oxidizing agent than copper. - **Explanation**: This statement is false. In the context of the reactivity series, zinc is actually a stronger reducing agent than copper. This means that zinc tends to lose electrons more readily than copper, making it a better reducing agent rather than an oxidizing agent. Therefore, copper has a greater oxidizing power compared to zinc. ### Conclusion - **Final Assessment**: - Statement 1 is true. - Statement 2 is false. ### Answer Selection Given the analysis: - The correct option is that Statement 1 is true and Statement 2 is false. ---
