25. A solution of a metal ion when treated with KI gives a red precipitate which dissolves in excess KI to give a colourless solution. Moreover, the solution of metal ion on treatment with a solution of cobalt(II) thiocyanate gives rise to a deep blue crystalline precipitate. The metal ion is (A) $\mathrm { Pb } ^ { 2 + }$ (B) $\mathrm { Hg } ^ { 2 + }$ (C) $\mathrm { Cu } ^ { 2 + }$ (D) $\mathrm { Co } ^ { 2 + }$ Answer [Figure] (A) [Figure] (A) [Figure] (C) [Figure] (B) (D)
