Which of the following statement(s) is (are) correct with reference to...
Ferrous and Ferric Ions:
- Ferrous ion: Fe2+
- Ferric ion: Fe3+
Correct statements:
B) Fe2+ gives blue precipitate with potassium ferricyanide.
- Potassium ferricyanide reacts with Fe2+ to form a blue precipitate called Prussian blue. This reaction is used as a test for Fe2+ ions.
C) Fe3+ gives red colour with potassium thiocyanate.
- Potassium thiocyanate reacts with Fe3+ to form a blood-red colour complex ion called ferric thiocyanate. This reaction is used as a test for Fe3+ ions.
Incorrect statements:
A) Fe3+ gives brown colour with potassium ferricyanide.
- Fe3+ reacts with potassium ferricyanide to form a deep blue colour compound called Turnbull's blue. Brown colour is not observed in this reaction.
D) Fe2+ gives brown colour with ammonium thiocyanate.
- Ammonium thiocyanate reacts with Fe2+ to form a blood-red colour complex ion called ferrous thiocyanate. Brown colour is not observed in this reaction.
In summary, Fe2+ gives a blue precipitate with potassium ferricyanide and Fe3+ gives a red colour with potassium thiocyanate.
