Answer:
+1
Explanation:
Molecular Formula of Tetraquadichlorochromium (III) is as follow,
[Cr(H₂O)₄Cl₂]ˣ
The oxidation states of elements present in complex are,
H₂O = 0 (Neutral Ligand)
Cl = -1
Cr = +3 (Given)
x = Overall charge
So,
[+3 + (0)₄ + (-1)₂] = x
[+3 - 2] = x
x = +1
Result:
Overall charge on Tetraquadichlorochromium (III) is +1.
