Which one will give Fe3+ ions in solution?
(a) [Fe(CN)6]
3-
(b) [ Fe(CN) 6] 2-
(c) (NH4)2SO4.FeSO4.6H2O (d) Fe2(SO4)3
ans is d but a can also give Fe³+ please solve my doubt......

Answer:
ANSWER
[Fe(CN)
6
]
3−
and [Fe(CN)]
6
4−
are complex ions.
They retain their identity in the solution.
Hence, they will not give Fe
3+
ions in the solution.
(NH
4
)
2
SO
4
.FeSO
4
.6H
2
O is a double salt.
In the solution, it breaks into individual ions, but it will give Fe
2+
ions in the solution.
Similarly, Fe
2
(SO
4
)
3
also breaks into individual ions.
Hence, they will give Fe
3+
ions in the solution.
Thus, option A is the correct answer.
Answer:
Hope it will help you
Explanation:
[Fe(CN)6]3− and [Fe(CN)6]2− are complex ions.
They retain their identity in the solution.
Hence, they will not give Fe 3+ ions in the solution.
(NH4)2 SO4 .FeSO4.6H2 O is a double salt.
In the solution, it breaks into individual ions, but it will give Fe2+ions in the solution.
Similarly, Fe2 (SO4 )3 also breaks into individual ions.
Hence, they will give Fe3+ ions in the solution.
Thus, option D is the correct answer.
