When a metal rod M is dipped into a aqueous, colourless conc. solution of compound N, which is a nitrate of metal ‘P’, the solution turns light blue. Addition of aqueous. NaCl to the blue solution given a white ppt ‘O’. Addition of aqueous NH 3 , dissolve ‘O’ and give an deep blue solution. The final solution contains [M(NH 3 ) x ] n+ and [P(NH 3 ) y ] m+ . (M) & (N) both belongs to same groups in periodic table. Calculate the value of x + y + n + m ?

Sol. Metal P is Ag & metal M is Cu.
∴ x = 4, y = 2, m = 1, n = 2
∴ x + y + m + n = 4 + 2 + 2 + 1 = 9
