Which of the following statements (s) is (are) correct with reference to the ferrous and ferric ions? (a). `Fe^(3+)` gives brown colour with potassium ferricyanide. (b). `Fe^(2+)` gives blue precipitate with potassium ferricyanide. (c). `Fe^(3+)` gives red colour with potassium thiocyanate. (d). `Fe^(2+)` gives brown colour with ammonium thiocyanate.A. `Fe^(3+)` gives brown with potassium ferricyanideB. `Fe^(3+)` gives blue precipitate with potassium ferricyanideC. `Fe^(3+)` gives red colour with potassium sulphocyanideD. `Fe^(2+)` gives brown olour with potassium sulphocyanide

Answer» `Fe^(3+)` produces red colouration with `KSCN` but `Fe^(2+)` does not give brown colour with `KSCN.
Therefore, (D) option is correct
