Answer:
Explanation:
Answer:
There is a
+
1
charge on the complex....!
Explanation:
But a FORMAL
+
3
charge on the iron centre....
SO we gots
F
e
3
+
FORMALLY bound to
2
×
H
O
−
ligands, and to
4
×
O
H
2
ligands....
We add up the charges....
+
3
+
2
×
(
−
1
)
=
+
1
....and so for the coordination complex we gots a formal cation, i.e.
[
F
e
(
O
H
)
2
(
O
H
2
)
4
]
+
...this is what we conceive to be the complex ion IN SOLUTION.. Were we to isolate it as its bromide salt, it would likely crystallize from solution as...
[
F
e
(
O
H
)
2
(
O
H
2
)
4
]
+
B
r
−
, i.e. a neutral bromide salt of the complex ion
Answer:
bromide salt is the answer
