Paragraph: When a metal rod MM is dipped into an aqueous colourless concentrated solution of compound N\mathrm{N}, the solution turns light blue. Addition of aqueous NaCl\mathrm{NaCl} to the blue solution gives a white precipitate O\mathrm{O}. Addition of aqueous NH3\mathrm{NH}_3 dissolves O\mathrm{O} and gives an intense blue solution.Question: The compound NN is

Options

  1. AAgNO3\mathrm{AgNO}_3
  2. BZn(NO3)2\mathrm{Zn}\left(\mathrm{NO}_3\right)_2
  3. CAl(NO3)3\mathrm{Al}\left(\mathrm{NO}_3\right)_3
  4. DPb(NO3)2\mathrm{Pb}\left(\mathrm{NO}_3\right)_2

Correct answer

A. AgNO3\mathrm{AgNO}_3
