JEE AdvancedChemistrySalt AnalysisMCQ+3 / −1
When a metal rod M is dipped into an aqueous colourless concentrated solution of compound N, the solution turns light blue. Addition of aqueous NaClNaClNaCl to the blue solution gives a white precipitate O. Addition of aqueous NH3NH_3NH3​ dissolves O and gives an intense blue solution.The final solution contains :

    [Pb(NH3)4]2+{[Pb{(N{H_3})_4}]^{2 + }}[Pb(NH3​)4​]2+ and [CoCl2]2−{[CoC{l_2}]^{2 - }}[CoCl2​]2−
  2. B
    [Al(NH3)4]3+{[Al{(N{H_3})_4}]^{3 + }}[Al(NH3​)4​]3+ and [Cu(NH3)4]2+{[Cu{(N{H_3})_4}]^{2 + }}[Cu(NH3​)4​]2+
