Passage / Comprehension

Paragraph:When a metal rod $M$ is dipped into an aqueous colourless concentrated solution of compound $N$ , the solution turns light blue. Addition of aqueous $NaCl$ to the blue solution gives a white precipitate $O$ . Addition of aqueous $NH_{3}$ dissolves $O$ and gives an intense blue solution

Question:The metal $rod M$ is

Options:

Answer:

Solution:

Appearance of blue colour on addition of the metal rod $M$ to the solution of $N$ is an indication that metal may be $Cu$ . Later formation of white precipitate on addition of $NaCl$ and dissolution of this precipitate in aqueous ammonia confirm that while preipitate is of $AgCl$ . This implies that the solution $N$ is of $AgNO_{3}$ . This confirm that the metal $M$ is only $Cu$ .
